Weekly Shonen Jump's latest issue reveals that Goku's latest Super Saiyan God form will be playable in the Dragon Ball Z: Extreme Butoden demo which can be obtained through a code in the next V-Jump or by seeing the film in Japan.

Dragon Ball Z: Extreme Butoden will be heading to the 3DS in Japan on June 11th.  No word of an overseas release as of yet, but hopefully Bandai Namco brings this game to the west.
