Ok first off guys, stop flaming. You're completely off topic. Although I pretty much feel the same way about MW2 being a PC only gamer I feel screwed over more than any of you console players.
Second. Treyarch DID NOT create the first three Call of Duty's. Infinity Ward created the first COD after having broke off from the Medal of Honour: Allied Assault team. The very first Treyarch made COD game was a rubbish XBOX1, PS2, Gamecube COD2 spin-off game, COD2: Big Red One.
Their first semi-successful full COD game was COD3 (I could go on to bag them for only bringing that to console and not PC but I shan't :evil: ).
Up until MW2 IW, IMHO, have made a superior game (we had zombie mods for COD2 and COD4 way before Treyarch came with their W@W zombie mode, although Treyarch is just a more polished off version, so don't go thinking I don't love it ). With IW's internal troubles during MW2 (nearly half the sodding team leaving :shock: !) it's no wonder MW2 turned out to be such a mess. That's just me speculating of course.
Have a look through this and the other parts following on talking all about Call of Duty's history. So please, anybody saying anything that is completely untrue, stop talking and because it's frustrating to read so many comments that are false.
Well after my little off-topic rant (hypocrite much? ) to comment on the subject on hand. Hard to say whether it is by coincidence or it was intentional. But there's isn't a whole lot in MW2's campaign that have really any cookies to suggest hints at BO's or any up coming Treyarch title (at the time). But very highly doubt an IW title would have anything to do with a Treyarch title.
