Website isn't official but it should be obvious that the game is anything less than confirmed at this point seeing as people like paying for the same game year after year. They're not just going to drop it.
Yay more Zombies, and a better balanced multiplayer. Treyarch ones are the only ones I ever like.
I also prefer the Treyarch COD games. Even though Black Ops seemed to be a step backward from WAW with no 4 player co-op campaign, no death cards, and way too much like MW2. Plus a crappy campaign. I have pretty much just given up on the COD series.
Its just not for me anymore at all. I prefer BF3 and Halo Reach. I will probably rent Black ops 2.0.01.2 but I havent purchased a COD game since COD:WAW. That was the last really good game of the series IMO.
