Call of Duty: Black Ops "Wager Match" Trailer

I have to say i was not convinced to the Call Of Duty Black OPS. I have watched live presentation on E3 via live stream video and i was not impressed. I said something like it is just a good game. And
"just a good game" was always for me an obstacle because it is like "you want to play the game but you don't want to buy it because it is nothing new" but with every trailer i feel like it will be a very good game. But for the game that i want to have mostly is Mafia II. Watch the trailer from multiplayer of Black Ops
