sure, I think the only thing that would make cube go flying off the shelves is if nitnendo released and online mario kart with worldwide rankings.
but in the grand scheme of things, nintendo owning the rights to megaman, street fighter, soul caliber, RE, Tekken, etc, would be cool... and just think, pacman, exclusive on GC
i think it would be good for nintendo. what they really need to do is release more mature titles.... and it is my opinion that third party games are good, but not as good as first party... i think the only third party game that is doing really good is madden...
