I agree the Wii wouldn't have sold as well as it has w/o Wii Sports. Many people saw his game and decided to opt for a Wii early on because it showed great use of motion controls. If it wasn't Wii Sports then it would've been something else anyway
I also think that the Wii still would have been Market leader regardless though. Might have been a closer race in the end but I give Nintendo a pat on the back. Sony should have done the same with a game pre-downloaded showcasing Six-axis and MS with 3 months free Xbox Live membership. Looks like Nintendo did the smart thing though.
