Most likely the 360.
That or Nintendo is going to have start churning out one new first party game every month.....
For the following reasons :
You're going to get 3 kind of third parties titles :
1) HD console support only
2) Wii support only
3) Cross platforms titles working both on Wii and HD consoles.
Titles from 3) selling 1 million+ on Wii will most likely sell 1 million+ on the 360 too so they won't help the Wii close the gap.
I don't see more million sellers from 2) than 1) in the next years.... ( even if publishers start massively supporting the Wii they won't drop HD consoles either..)
PS : even if the Wii hardware lead over the 360 gets incredible, in the end the issue is that you don't need a 60 million console install base to sell million sellers, you can do it pretty well on a 15-20 million console bases like the 360 has been demonstrating.
My answer would be different if the question was how many 5 million+ sellers. The Wii will win that hands down..
PS3 can't win because at this point 95% of the crossplatforms million sellers on the PS3 will be million sellers on the 360 too and I don't see Sony managing to get 30 more million sellers exclusives out this gen than the 360...
