When will GOW 2 surpass GOW 1?

[jpain333]

I honestly doubt Gow1 is overtracked, months ago I read an interview on CNN.com with that Cliffy B guy and he said the game sold 5.5 million copies....

Anyways on topic I can't say I know, I mean the first game is still selling very well, GoW2 will slowly catch up but that will take a while.
