The transformation is colloquially referred to as Super Saiyajin Blue. Not much is known about it, other than this rather nostalgic teaser above that features the logo appearing on a classic PS2-era CRT television, which gives way to Goku undergoing his more recent blue-haired transformation from Dragon Ball Super, called Super Saiyajin God Super Saiyajin (yes, they really do say Super Saiyajin twice).
The new game is in development at Bandai Namco in partnership with the show’s long-time production company Toei Animation. The series’ last outing on a major console was Dragon Ball Z Budokai Tenkaichi 3 on the PlayStation 2 in 2007 (though it wouldn’t make its way to Australia until 2008). The new game will become the fourth entry in the franchise and the first new game in the series since 2010’s Dragon Ball Z Tenkaichi Tag Team on the PSP.
