I agree with the "new gen" label since they (nintendo) are going for something entirely...well, new. They are moving over into a niche of their own.
Imagine three cars traveling down a freeway in the same lane, no one is really going to get anywhere since they are riding each others butts...
but if a car (nintendo) were to move into another lane, even if it led somewhere else (innovation), they would be able to pull out in front of the other cars (competition).
Maybe it is a hard analogy to follow, but I kind of like it...and I made it up on the spot so forgive me if it's a little weak.
btw...I'm 19 and going to college in the fall, and I happen to enjoy all ratings of games: E,T,M. People shouldn't feel like they have to play an M game in order to be mature. Let the rest of the gamers follow one another...the Wii is for individuals.
