How many GPUs will Sims 3, Starcraft 2 and Diablo 3 sale

[canch]

I used to play diablo II and put 100s of hours into it.  I belive Diablo 3 will sell 4 - 7 million over it life time and The Sims 3, well im thinking like 8 million over its life-time.  Dont know about Starcraft as I never played it.
