well MikeB I thought that this is done by many people, I expected that great Cube games would get sales boosts because people are buying the wii that haven't owned a Cube, but this market seems to be tiny because I don't see it happen, stores are only selling out their stock of Cube games and are removing them from the shelves.
and about launching later: I'm very sceptical about this. It is very rare that a console can makeup a gap that existed because of a headstart of a competitor, and the Wii would have gained a lot of steam during this one year of headstart. I think you either have to be as early as possible, or you have to skip a generation.
