This may be a little vague and confusing, but I feel I may have figured out a few things about the Halo 4 campaign.
Firstly, the villain in Halo 4 I believe is the “Didact” who was the husband of the “Librarian” mentioned several times by 343 in Halo CE. He was the forerunner military commander who placed his consciousness inside a Builder before the Halo rings were activated for the first time. We hear 343 refer to “Him” during the terminal sequences of Halo Anniversary and Cortana say “we know where He is going…” during the Halo 4 gameplay demo (in reference to the large forerunner sphere or Promethean Cryptum). We hear him speak at the end of the trailer “I have long dreamt of this day, Reclaimer.” We already know he was in charge of the “Prometheans,” an elite forerunner army who have been confirmed as the enemies in Halo 4. Also, the Dyson Sphere was his idea as an alternative protective action against the flood, instead of using the Halo rings that he considered a terrible sin. What they wan’t ultimately, is hard to say, but it could be the reanimation of the Forerunner species. Being that humans are known as the “reclaimers,” referring to their ability to appropriately use and “reclaim” Forerunner technology- it’s safe to say Master Chief will be getting his hands on more of their technology and gain a better understanding of their society.
That being said, Cortana will play the other villain in the story. Although, Spartan 117 and she have a strange romance, she is losing her control as an aging AI. She is beginning to go rogue and a little insane, which we see in the Halo 4 gameplay demo. During Halo CE, the first time she is entered into Master Chief’s helmet, she says “Your systems aren’t unlike the Autumn’s” to which he responds “Don’t get any funny ideas…” She is of course referring to he ability to control the Pillar of Autumn ship they arrived on and being an AI she doesn’t have a body of her own to actually attack Master Chief. I believe she may take control of his suit and use it against him as a vessel for her digital self. Meanwhile Master Chief will “reclaim” a new Forerunner suit that affords him new abilities and access to more areas of the planet. That or, being that the Prometheans aren’t biological lifeforms, Cortana may instead take command over them to use against Master Chief.
These are only theories, but are ideas that so far seem to fit the overall structure of the game and what little gameplay elements we have been shown so far. Let me know what you think or if I’m missing something that either further proves the theory, or instead makes it less likely. Either way, I think we can all agree that 343 studios is doing an amazing job and Halo 4 cannot come out soon enough.
I think the Cortana part is right But I’m sure she won’t try to kill him.
I agree that 343i is doing a great job with Halo 4, but it hasn’t been confirmed yet if the Didact is in the Cryptum or if that’s him talking at the end of the trailer. Plus the Didact isn’t evil.
I realize it isn’t confirmed, thus the topic title being a theory. However, it seems to fit rather well and makes a lot of sense towards the overall story arc. I also am aware that he isn’t evil, but the same can be said about the Covenant who are simply pursuing their religious beliefs in the Halo rings and the Flood as well who are just insatiably hungry. That’s what makes the Halo series so good, each side has something to fight for and being that Didact didn’t originally want to fire the Halo rings, he perhaps would want to “undue” the destruction they caused.
Maybe not kill, but keep at an arm’s length or even stranded on the planet as in the glimpse shown to us during E3 she screams “I will not allow you to leave this planet!” It’s tough to say how their relationship will pan out, but 343 has already confirmed she will become something of a problem for Master Chief.
OP please don’t just jumble everything together next, it really hurt my eyes.
My bad… I actually organized it into paragraphs, but this forum doesn’t recognize indented text apparently. I’ll edit and fix it if I can.
I do believe the issue that you propose about cortana is solved in a statement in the book halo fall of reach where docter hasley states that there is a buffer placed between cortana and the suite that does not allow her to take control
btw sorry of any spelling errors im tired
Just thought of this… You know how Cortana says “I WILL NOT ALLOW YOU TO LEAVE THIS PLANET!!!”
My question is
Who says Cortana is talking to the Master Chief?
That is all

The Prophets set out to kill Humanity to keep their power and their Covenant together, because if the rest of the Covenant found out that Humans were Reclaimers and the religion was a lie, it all goes away.
The Didact being evil and having no characterization for his transformation into the villain wouldn’t really help the story arc, though. I definitely agree that each side has something to fight for, though 
The Didact parts are all true, except he imprinted his mind into a young forunner explorer (Named Bornstellar) and was THEN executed by the Master Builder, who believed in firing the Halo rings. The Didact believed in finding refuge from the flood in shield worlds rather than fire the Halo rings, hence why we find the Bornstellar version of the Didact on the shield world, Requiem.
It is also known that if the Didact is awakened by the firing of a Halo(s), he will go into a rampage if the Librarian is not there to monitor his behavior. It is unknown as to why the Didact has taken a sudden evil turn, especially since Master Chief had destroyed the Halo Array and the flood.
Although… I do expect Cortana to turn on Master Chief.

When do we find the Didact on Requiem?
The Didact isn’t the Librarian’s test subject; they were lovers. I don’t think it’s “known” that the Didact awakes from the firing of Halo and goes on a rampage, by the way…

You know the Didact is the enemy on Requiem because
A) It’s his symbol thats being displayed everywhere.
B) He believed in refuge on the shield worlds
I know they were lovers, and being his wife, she kept his temper under control.
Also 343GuiltySpark says in the Combat Evolved Terminals that he will be in rage if he is awoken and a Halo ring has been fired. He knows this because of his personal experience with the Didact as Chakas, the human.

All the signs pointing to him are very odd, yes. His symbol is slightly different than the one at the end when it says “An ancient evil awakens.”
I know what Guilty Spark says in the CEA terminals, but it’s just very peculiar. There’s no evidence whatsoever to support the Didact being “enraged” by the firing of a Halo ring. Plus, who could he have a logical reason to be mad at? I completely get what you’re saying, it’s just very odd, is all.

343 Industries has left the book readers hanging as to WHY he has become evil. If you see at the end of the trailer, its his symbol but its just upside down, representing his change to become evil. I would assume he is enraged because he believed in refuge of the shield worlds and was against the building/firing of the rings. However I don’t see why he would continue to fight the Humans when they had actually destroyed the rings…
