1) You are still making the same mistake. You can't compare the sales trends of SMG to SMS, because SMS was clearly handicapped by a lower average review score. =)
2) 4 % in score is nothing in the sub 50 % regions, but when the scores you are comparing are both in the 90+ % range, then 4 % make a huge difference as the SM64 vs. SMS sales comparison clearly shows. =)
3) So, just because Wii sells as good as PS2, doesn't mean that the PS3 will sell as good as GC. =)
A review score over 90% is hardly a handicap. I would call that a very good score, actually. Reviews do not impact sales the way some people think. For example, smash brothers isn't over 90%, yet people love that game. Back in that those days, bashing Nintendo was the hip things to do; that's why a lot of the GameCube games are underscored. There's a simular thing happening to the PS3 right now.
