As others might have mentioned there are M rated games on the way; Disaster, Fatal Frame 4 and MadWorld are some of the more noteworthy games.
Out of curiosity I was looking at the ESRB site to see what number of M rated games each Nintendo console has.
NES 0
SNES 6
N64 25(they list Eternal Darkness here, it's a mistake)
GameCube 47
Wii 19(one is a VC game)
Since the ESRB was formed in 1994 many games for the NES and SNES probably haven't received ratings.
