With the increase of online multiplayer, I highly doubt that this move would push more hardware than it would hinder. One thing, for instance, that pushed Wii hardware sales was the need of two systems to be able to play three plus players online on Mario Kart Wii. And for Super Smash Brothers Brawl you even need two systems for two player co-op!
Of course there are positive sides as well though, but currently I think this move would do more harm than good (well, at least financial harm for Nintendo).
