He doesnt have a SSJ2 cause there is no model for it yet.He doesnt go ssj2, he only goes USSJ (Ultimate Super Saiyajin). Vegeta willbe getting SSJ2, although I'm not sure why they havent implemented it yet. Perhaps they plan to do something special with it.
BTW, to the devs, his USSJ hair is supposed to stand on end much more...
And what kind of new transform system are they going to have? I've not heard a word of that yet...
Probably. But all efects still have to wait for the FX script to work properly before anythign happens ^^Are there gonna be default effects?
