Nintendo has a pattern of overdelivering with the consoles, and then underdelivering with the games available for said console (at least at first).
EDIT: I should add that this is a relatively recent pattern; the N64 and the Game Boy Color are definitely stronger as platforms (with all their available games) than as consoles. Somewhere between the Game Boy Advance -> 3DS (which has terrible game availability for an awesome console) and the GameCube -> Wii, the pattern reversed itself.
