First of all, don't get your hopes up people, I seriously doubt there is another smash game coming for awhile. Even if their was, remember how long brawl took to make?
As for another console generation, I think nintendo, microsoft, and sony are all waiting for televisions with stereoscopic 3D to become mainstream (think 3D movies in theaters now) because that will most likely be the next big gimmick, every generation needs one.
Doubt it, even with DS's graphics, I sincerely doubt we will ever have a handheld smash, it greatly lowers to possibilities. I mean, compare the few buttons you have with a DS to the GC, you definitely have more options with a GC, even if Smash is a fairly simple game. You only need 2 of those buttons for a smash game, you need shield buttons, and a C-stick. You also need jump buttons. IE, I would hate a DS smash and I think Nintendo realizes that.
um, they made smash to be played with a wiimote, it isn't good, but if they were willing to do that I doubt a DS would be a big deal to them.
A DS game while highly unlikely COULD actually be really good if done right. Think about it, smash isn't about graphics, it's about gameplay, they could theoretically make the gameplay and online a lot better than brawl currently is.
as for the controller, you have directional input, 4 face buttons and two shoulder buttons, that is all you ever use in brawl, I don't know where you are getting this "more options" business.
Still, I doubt it, and yet this does seem to be hyping smash bros from Nintendo, so it's confusing, it wouldn't have been a big deal unless he hadn't mentioned newcomers, that's what is really confusing about this, we'll have to stay tuned to see if they say anything else.
