Now that an official website has been set up for the game, we actually have some confirmation on certain things!
The upcoming fighter for the Xbox 360 & PlayStation 3 is indeed being developed by Dimps and has actually been in development for a bit (Dimps is not exactly rusty, either; the “Shin Budokai” and “Arcade Impact” games have kept them busy with the franchise). As Julian stated in the latest podcast episode, it will be featured in playable form at the upcoming Jump Festa this coming weekend. There are two screen shots over on the website — one looks like something either from a cut-scene or super-move, while the other is that Goku vs. Freeza shot we have already seen.
