I don’t really mind what they do to the gameplay, so long as it’s good and enjoyable.
I’m more concerned about story, to be honest. I’d like to actually have a good story with a decent length this time.
I wanna use the Jackal shield. MC should be able to rip it off a Jackal’s arm and use it. lol.
Also If he comes in contact with any Spartans or marines, we should be able to fight along side them. I’m talking about having a huge unit that grows and grows till the game ends. I like keeping my marines alive : D

I want a good story, too. Nothing like Reach (which I thought was horrible, sorry). Scatter lot of easter eggs throughout as well and don’t discourage the communities desire to get out of maps. Make epic set pieces that scream, “explore me!” 
As for gameplay, no bloom or AAs, please. No sprint stuff either. Keep it simple and basic. Return to the arena style of gameplay that Halo 2 had.
I’d also like to get my hands on some forerunner weaponry.
In terms of gameplay, I want a blend of the traditional and Reach systems.
A full sandbox editor would be nice too.
Increased player count for Firefight would be good as well (This site has it listed as four though).
id like to see the flood, a halo CE style assault rifle with 60 rnd clip along with a halo CE M6d pistol with halo ce power and lethality i would also like a warthog n a scorpian
Anything that isn’t like Reach’s story. That’s for sure.
I personally have no problem with Reach’s system. In multiplayer I would like no AA’s though, except I think sprint should be a default ability for all. I feel so slow if I’m constantly stuck at the same speed as the person in front of me.
I think assassinations should be included.
I think that all of Reach’s weapons should be included, except perhaps the Plasma Repeater and the Focus Rifle (which should be replaced by the Beam Rifle).
Then again, if the Covenant aren’t an enemy it would probably make little sense to have these weapons play a large part in the multiplayer, unless of course, in some part of the campaign, they ally with the humans against the new enemy.
-No armor abilities,This is Halo 4! Sequel to Halo 3,One of the real Halos,anyway,Sprint would be cool,At least in campaign
I want ODSTs Firefight + Reachs Firefight 
-Better Forge,Forge v3?
-A better 1-50 that is much better then H3s and H2s
-Armory with new armors and old armors
-Better Maps
-Big firefight with alot of vehicles (i mean vehicles like scorpions,falcons,hornets)
And also about the campaign.
I really hope that chief lands on Onyx/Dyson sphere/Shield world in Halo 4
Think of it! That would be really awesome,
Since the ghost of onyx sequel will not be about Onyx 
Sooo…
@ The OP
Yes to all! Screw AA’s and give me my BR!
I think we should be able to customize the Chief’s armor and gender just like Noble Six.
the armory should stay and credits which you get after every game but only for armor, and the halo 3 exp reward system as your “exp” rank, but every playlist has visible true skill so everyone knows how truly skilled you are in that playlist also an overall true skill and highest skill does not contribute to ranking up, this is only because i was stuck at 41 highest skill in halo 3 and i got bored of being a colonel.
also if they bring back the br it should have reduced fire rate and hitscan as it was overpowered in halo 3 and halo 2
i also think assassinations should stay and if they keep bloom they to implement correctly into the game im not bothered if it goes or stays
and to the op if you watch the halo 4 trailer closely you will notice master chief has a new weapon which looks like a sidearm grenade launcher
and bring back ranked and social
> I think we should be able to customize the Chief’s armor and gender just like Noble Six.
armor maybe but i feel that could ruin his identity and gender for your multiplayer definetly but not as chief
I’d love to see that ALL weapons have headshot-capability. I mean, if a bullet hits the head of an unshielded Spartan, it ought to kill him instantly because it really should not matter from what weapon the bullet was fired. Headshot is headshot. And this should also apply to plasma weapons, needle weapons … ALL weapons, really.
Next, I want all these idiotic spray-and-pray weapons gone, first and foremost the assault rifle. I hate it with a passion, and it hurt multiplayer more than armor abilities. If you can’t score kills with weapons like the BR, DMR, carbine. needle rifle, or magnum, don’t play a first-person SHOOTER. Go back and play H3 and Reach, because that are first-person SPRAYERS.
Return of Silenced SMG, flashlight (on weapons, useable on customs), night vision, The flood returning, balanced sandbox, etc

Noo way… That would be stupid,Chief is chief!!

I think the Spartans do that in Ghosts of Onyx.
Flood
Forerunner’s first game appearance
Ability to use Forerunner weapons/tech
Percursors, maybe
Maybe Covenant, but save them for 5 or 6
Another monitor like Guilty Spark
A shield world like in Wars, maybe the other 5 unexplored rings
A huge sense of mystery like in CE and ODST
Maybe a little bit of fear
Maybe a little more personal and not-so-epic
sweet
A variety of weapons that actually matter and are balanced, and Sprint but no other AAs
