Well, that's just complete nonsense.
PS3 exclusives rated above 90:
- Uncharted 2
- LBP
- MGS4
- LBP2
- God of War III
- MLB 10
- Killzone 2
- MLB 09
And if we go down to 85, there are plenty more. That's not even counting the games that it shares with 360 and PC, but which are not present on Wii.
My point isn't that the PS3 has a better exclusive library (though, in my opinion, it does) but rather that any sort of list like this is completely subjective. Suffice to say, in the eyes of critics, the HD console libraries are stronger than that of the Wii.
EDIT: To back that last statement up, the number of 90+ metacritic titles by system:
Wii: 11
PS3: 31
X360: 36
Perhaps that's just down to reviewer tastes, but if that many people disagree with your conclusion, it's probably not set in stone.
