GameStop.com now has a listing for a “Transformation 2” on the GameBoy Advance, with a date set of 15 November 2005 (right around the same time that “Sparking! / Budokai Tenkaichi” is due out). This would be the fifth game in the “Legacy of Goku” series of action/adventure/RPGs (which randomly stopped using the “Legacy of Goku” main title after the second game).
The first “Transformation” game, which will span the beginning of DBGT through the Bebi arc, is not even yet due be released until 19 July 2005.
Thanks to forum member Kodoshin for the heads-up.
