Halo 4: ODST with the return of Buck and other characters, Firefight 3.0 that can be played in matchmaking, and a fixed Forge with all new building pieces that can be used to make FF maps as well as anything else.
Keep dreaming 
No but really, that sounds awesome… unlikely, but awesome.
Halo 4: ODST?
No.

Whyyyyyyy?
odst was epic and the most under rated of all the halo games. Even tho it was somewhat of an extension, the firefight was epic because it felt like you really had to fight to survive, and the campaign was rather good as well but of course everybody will disagree
If firefight is coming back, i think we should be able to play firefight on EVERY map in the game. spartan ops has multiplayer maps in it, and gears of war’s horde mode can be played on all the maps, so why not? Maybe even the ability to forge firefight maps! the replayability would be near endless! if this gets implemented in a future halo game, it’s gonna to be my favorite game of all time, unless they manage to screw everything else up.

Not sure if you’ve noticed, but if Buck were any better, he’d be a Spartan.
That, and Halo 4 kind of lacks ODSTs. Plenty of Marines for some reason, though.
So, Halo 4 : Marine? OH! Or, Halo 4 : Eggheads! Where you play as a scientist.
