Just because it uses the Wiimote/Nunchuk doesn't mean it's a random waggle heavy game. There are buttons on those controllers.
Games like Guilty Gear, RE4 Wii, Godfather, and Zelda have all proved that traditional games can be done well. That isn't really argueable. The wii can play a traditional 3rd person action game just as well as the GameCube/PS2 could, and we never had any problem with their ability, right?
I really like Nintendo's strategy of staying just a bit behind the curve. Because when we see the next nintendo console, they'll adapt even more of what was cutting edge today, for an affordable price, probably less than the 360/PS3 have gotten to, except Nintendo can market their system as new, which is an advantage to them.
And sarasugi, I appreciate your post, and your opinions, but saying that because Nintendo has captured the mainstream, their console isn't relevant is just plain dumb. Nintendo is laughing, laughing all the way to the top. I'd wager to say that joe wal-mart shopper (the very demographic which gave Sony its success PSOne and PS2 generations) is now a PS2/Wii owner, and will not be a PS3 owner. Not anytime soon. This is so ironic, because Nintendo is now doing to Sony what Sony did to Nintendo about decade ago with the playstation. Nintendo fans cried the same way about diluting the market, and the poisoning influence of the mainstream.
Comparing an $80 portable that's been selling very well for 6 years, without nearly any software coming out for it to a brand new, high def, multimedia gargantuan like the PS3 is not exactly fair, but it's telling of what people want.
I think the biggest effect that the Wii is going to have on the future is reduced emphasis on hardware, and maybe longer generations before a platform upgrade. Although you could attribute the second one to the PS2 as well. I think they're both good ideas. You don't see a new movie format coming out every 4-5 years, or new music formats..
Who knows, I just find it interesting to think about what the future will hold. I'm drooling over Halo 3 and MGS4 just as much as anybody, but I've gotta admit that things are getting out of hand cost-wise.
