The delay is to prevent piracy. It only takes mere minutes for a game to be available for download on pirate sites after the game is put on the shelves. Some game publishers release a PC version later so fans are inclined to buy them for consoles first (or instead), as Console games are pirated as well, but far less than PC games. If you're a fun of the game or the developer's, please do realize that the delay isn't meant to tease you, but to help creating more fun games in the future.
3 months delay does activision not knowing that about 75% gamers use pc, yeah i know that the consoles ps3 & xbox 360 use to petent them for late release on pc for increasing their sales but why wwe only use to suffer always.
they want you to get tired of waiting and buy it for your console then buy the pc release after you see it is much better.
can't wait to play this on my pc. i just don't understand why they didn't release this together with the consoles... T.T
