Here's a quote from Infinity Ward about some rumors.
People. This list is fake," posted Infinity Ward programmer Rayme "Rayme" Vinson. "I mean; I can't get into how-much-if-any is true, how much is false, etc (there's a reason why companies "don't comment on rumors"... it would NEVER F***ING END), but this list wasn't put together by anyone with any insider information. There's also some craziness that should red-flag this as "stuff I made up and wrote down" (like grass camo for snipers... that's straight out of CoD4 MP)."
Vinson was backed up by studio community manager Robert "fourzerotwo" Bowling.
"I preferred when rumors were ground breaking, like when we were making that Sci-fi Stealth Assassin game in space," joked Bowling.
