User blog comment:FireBird-/MW3's new Survival Mode Revealed!/@comment-3255814-20110528024517

I wish Infinity Ward would just come on out and say they're now putting a Treyarch contribution in their game. That's what Treyarch said when they put the multiplayer systems from COD4 in World at War. But, no, they have too big of egos to do so. I wouldn't be surprised if Theater Mode or Wager Matches weren't in MW3.

Still, they game's only just been announced, so maybe they will fess up in the future. Treyarch has openly included contributions from Modern Warfare in their games, so now it's time for Infinity Ward to get off it's high horse and do the same.

P.S. A "derelict Cold War-era desert radar command bunker"? Err, the game's called MODERN Warfare.
