I think xbox 360 will win comfortably because a lot of the iffy multiplayform games are much more likely to sell 1mil on the 360 imo such as rage and dues ex,while the multiplatforms that will sell better on the ps3 likely won't make 1million this year on either system such as dark souls and need for speed(since it only has 6 weeks to sell 1mil which only Hot Pursuit has been able to do in the need for speed franchise this gen.
As for games that you didn't mention that have a shot at passing 1mil this year.
AC brotherhood will probably pass 1mil on both 360 and ps3
nba 2k12 will pass 1mil on the 360 and probably pass 1mil on the ps3
Fifa 2011 will probably pass 1mil on the ps3
Bulletstorm, Brink, and Dragon Age 2 for the 360 all have a shot at passing 1mil on the 360.
Marvel vs Capcom 3 and Sports Champion have a shot at passing 1mil on the ps3.
With ps3 holiday bundles god of war 3 has a shot at passing 1mil
I don't think Just Dance 3 has any chance of passing 1mil on the ps3 or the 360.
In the end I think xbox 360 will have 30 1mil+ sellers while the ps3 will have 26 1mil+ sellers
