We all know Forza 3 is coming, just about the worst kept secret in the gaming industry and through a miracle GT5 will also release....day and date with GT portable. -_-
So with that said, predict lifetime sales for Forza 3 and GT5. Advantages Forza 3 has are that it releases on a console with an install base 8 million higher than the one GT5 will release on. The advantage GT5 will have is that Gran Turismo will be in the title. Both titles have the advantage of being bundled of that no question can be asked.
GT5:
NA: 3 million
EU/PAL: 5 million
Japan: 2 million
= 10 million
Forza 3:
NA: 2 million
EU/PAL: 2 million
Japan: 0.3 million
= 4.3 million
Those are my predictions without bundling
