The official Japanese website for the latest Dragon Ball game on the PlayStation 3 and Xbox 360 has been updated recently and in the splash is Majin Vegeta! There isn’t any information on him other than the fact he will be in the game in some shape or form, but our bets are on the notion that he will be playable.
The website update also reveals another interesting tidbit of information – in Japan the game will be called Dragon Ball: Ultimate Blast rather then Dragon Ball Z: Ultimate Tenkaichi, which will be the official name in North America and Europe. No reason for the name change is given, but if we had to guess there was probably some kind of licensing issue. If you have ever noted, the Dragon Ball Z logo always differs in English-language video releases (which are by FUNimation) when comparing with the Japanese (which are by Toei Animation).
Also, Japan will be getting Dragon Ball Z: Ultimate Tenkaichi (or Dragon Ball: Ultimate Blast, actually) on December 8, over one month after the North American and European release dates of October 25th and October 28th, respectively.
