: Unless by major releases you mean new Master Chief titles

Yes, I mean new major Halo universe FPS titles with or without MC.

ODST is an example of what I think 343i is more than capable of producing on a short production cycle if they have planned properly.

They've known their platform longer than anyone and their new engine could essentially be cast in stone for the next two or even three releases. Perennial releases should be possible and I believe are now more necessary than ever. COD's franchise has ramped up its production schedule and it has paid off. COD is in the news and in your face every week.

Halo franchise ... let's do remakes to kindle two/three months of interest from deserting fans. Poor man's solution at best.

Starting with Halo 5, I hope to hear of a new release each year for the next three years. That's how Halo will regain top spot again.

Quote Wikipedia:
"Bungie began development of ODST in March 2008.[39] ODST was the first Bungie title completed in less than three years,[40] as production lasted 14 months.[41] Since the team—numbering around 70, plus a five-person core design group[42]—had such a small window for development, they had to prioritize features; for example, rather than completely redesigning the enemies, only a small new subset of artificial intelligence behaviors were added."
