Halo is coming to the Xbox 1, but if it was Halo 5, why not call it Halo 5.
So perhaps this 2014 release is actually Halo 4 Part 2?
343’s game plan could be to release Halo 4, 5 and 6 at 4 year intervals, with a Campaign expansion every 2 years through DLC or possibly even retail.
Halo 4 - 2012
H4 Part 2 - 2014
Halo 5 - 2016
H5 Part 2 - 2018
Halo 6 - 2020
H6 Part 2 - 2022
I know this makes it seem like a long time till 6, but you don’t want to eat your dinner too quickly 
As Halo 4 is not on the One, it would likely come packaged as a complete edition, so you wouldn’t have to swap consoles to play to half’s of the same game.
Regardless, I’m SUPER FREAKIN’ PUMPED for it and can’t wait for more info!
Honestly this is an interesting take on things. I doubt it personally, but its still a possibility, especially since it goes over an exact 10 year period.

Plus, the One will likely have a life span of 10 years or so, so it would fit well.
Um i would like to think this generation is going to last at least 15-20 years
Room for trilogy number 3 then? 
I like the idea OP, but Microsoft is calling the trailer, “Halo 5 trailer,” so I assume it will be Halo 5. I could be wrong though.
Haha ha… ha … ha
It would be ridiculous if this was true. I’m not going to pay more money for a stupid “Campaign Expansion” as you rumor.
If so, it’s no better than Battlefield 4 at the moment.
!!!PREORDER AND YOU’LL GET ACCESS TO LIEK 2 OF OUR FULLY COMPLETED DLC PACKS THAT WE COULD HAVE EASILY INCLUDED IN THE GAME BUT DIDN’T BECAUSE WE WANT YOUR MONEY!!!
