While already unveiled internationally as “Ultimate Tenkaichi”, the upcoming PS3/360 fighting game formerly known as “Game Project Age 2011” has finally been given a formal name in Japan: Ultimate Blast.

The game, now with a name calling back to the prior two Raging Blast games in its home country (themselves an extension of the Sparking! series), appears to be due out in Japan 08 December 2011 for ¥7330, a good six weeks after its international release. Will the extra time bring any bonus content? We will keep our eye on it!
