GBA is not being replaced. I don't know why people keep saying it is. Nintendo has already stated that the next iteration of GB is being developed. I have seen people, not just kids, playing GBC and such games on their GBA. DS cannot play anything older than GBA games. So for anyone who still has those games, they must get a GBA.
I don't know how many of you realize, but the launch titles for DS are mostly from 3rd parties. Nintendo has the MP: H First Hunt demo, and SM64DS. Thats it for the US. Madden, Spider-Man 2, Urbz, Feel The Magic are all 3rd party.
There is only 1 port on the DS so far. That is the N-Gage port of a racing game. The rest are all new games. So quit yer bitchin about it.
If you have not heard about Advance Wars, then you missed out on at least hearing/reading about 2 of the best games on GBA who both have earned a 90%+ on gamerankings..
I see lots of people saying that the touchscreen is a gimmick. Well to put it in comparison, lets say that I think that Tivo is a gimmick. Why should I buy that when I have a VCR? Its something that you have to experience. All I have heard from poeple once they get Tivo, is that it is awesome and couldn't imagine life without it again. Having so much control over the game, and a different type of interaction is what gives the DS and all its features its need for experience.
The DS was arguably the most talked about item at E3. The only line that might have been longer was for HL2, and that was only a video demo. DS was something you could actually use, and play. For the same people to wait in the 2+ hour line each day just to play it again for a few minutes speaks volumes. And that was before the retooling which made it better.
The handheld that will "win", will be the one with the best total package. That means games, battery, hardware, et al. People were saying that the GBA was gonna take a huge hit when the N-Gage was announced, well we all know how that went. Honestly I am impressed with the PSP's screen briliance. But hardware doesn't sell me. The DS has more features, BUT, I know that the games being made for it will be more unique in one way or another.
Sony is making a run for it full steam ahead. I think in NA though, the bout half year headstart the DS has will give it a lot more exposure than some people may think. It will be interesting to see how things turn out.
