How many 10 Million Sellers will 360 get this Gen?

[Apollian]

I believe that the 360 will sell 4 or 5 titles over 10 milion.

Question is, how many PS3 games will sell over 5 Million in this Gen?...my last 12 games have been for the 360, I will be buying GT5 for the PS3, but outside of that, I can't see my buying much for Sony's console.
