Tale Tale Source (as translated by Andriasang), the upcoming issue of Weekly Shonen Jump includes an announcement of a new entry in Namco Bandai's Dragon Ball fighter series. The game, which is (assumedly tentatively) titled Dragon Ball Game Project Age 2011, is reported to focus on "3D fighting action," a blanket descriptor which could easily apply to the many Budokais which have come before it.
The blog also mentions that the magazine lists Dragon Ball Game Project Age 2011 for a Fall 2011 release in Japan on Xbox 360 and PS3. We'll keep an ear to the ground for any news about the title and its American launch plans. Considering how loud those Dragon Ball guys yell, we don't think it's going to be too hard to hear.
