good one, but i think u'd probably list it properly already. Now, my personal opinion to your question is that the media which they use defines the next generation. hence, like ps3 to bluray, xbox360 - dvd/hd-dvd, wii - let say its the wii-remote (they did state that they're not trying to get into a media usage war, they're more on to innovative-ness)

maybe thats just my opinion. anyone has a better idea?

hah! like i said, nintendo wants to stay clear of the media usage. they always do. look at gamecube...somehow or rather, its different. lets put it this way. would u say psp in 3 years time, comes psp2, would u call it a next-generation? if not...then why not?

its like that. there's always an improvement. thats when the word "next" comes to play.

by the way, u got me there about the n64 thing...it was so crappy, i almost forgot about it. hahahaha
