Halo 3...
Halo: ODST has a chance if it is succesful and advertised and bundled..
Halo: Reach will most definetley hit 10million in its lifetime if advertised as much as Halo 3. It is essentially Halo 4, but a prequel. I'm not sure how many people will realise this though considering it doesn't have a number slapped on the end and not everybody knows what Reach is.
Pehaps Forza Motorsport 3 will if again in the same situation as Halo: ODST.
Oh and Modern Warfare 2 definetly has a shot even though it is missing the Call of Duty from the title. Also Grand Theft Auto V will most probably hit 10million+ if it is ever released this generation and made more like Vice City/San Andreas.
