To be honest, it doesn't look much different from the first game.
Sure, some grass and more light-effects where added and the camera moves differently, but that's pretty much it. Nothing impressive considering that this game will be next-gen only, unlike the first one.
I'd like to see how much they improved the character-creation, since that's the core of the game. Almost everyone will play with custom characters anyway. Also, I want to know if they fixed the awful reward (item/skill drop)-system, the tiresome random rewards killed the first game for me. As well as the super-saiyan ki-spam. No one needs that in a game that is supposed to be balanced.
Wrong section btw.
