Bah, is that all you think about? Your precious characters? I see it like this: Some characters won't be announced till after game release, so that would mean since there will be some more characters announced before the release, we'll have a lot in the end. They have to keep some of it secret. Sure, there could be more character updates, but the game is more than about them, it's how they tie to each other in the game and the enhanced one-player adventure mode is THE chance to do so. We pretty know for sure that this time this aspect of this game will be much better than Melee. Then there's the music, the gameplay, the items etc. etc. Expecting only character updates...you must be pretty disappointed by now, where's the fun in that? ;P Try to be more positive, people.
And I have to say, the graphics in the video just scream Final Fantasy. It's a blast. Like someone else mentioned on here, this clearly shows that the Wii's graphics aren't bad, in fact, they are more than decent.
