The Magic Box is reporting that Banpresto will release the System 246 arcade fighting game “Super Dragon Ball Z” (developed by ex-Capcom producer Funamizu, along with his studio Craft and Meister) on 22 December 2005 in Japan. The game’s official website is also up, and has tons of great stuff on it — you can find a character gallery, some basics on the fighting engine, and more.
There is no word on a home release as-of-yet, but since System 246 is based on the PlayStation 2 hardware, an eventual home release (at least in Japan) seems likely.
