Bandai has put out a press release talking about their 2008 plans and showcase from the 2008 American International Toy Fair. Here is the part you are all interested in:

DRAGON BALL Z® – Bandai America celebrates its triumphant return in 2008 as master toy licensee for Dragon Ball Z, considered one of the most successful anime properties from Japan for over the last 11 years. Fans of Goku, Gohan and all the Dragon Ball characters will have access to exclusive products in the Spring, including 4” collectible figures and highly detailed 2.5” figures direct from Japan. In the Fall, kids can build their ultimate Dragon Ball Z collection with exciting new toys designed for the U.S. market, like the 2.5” Flash Changer Figures that transforms characters into their energized forms, and 8” Power Boost Figures, with muscles that expand and break through the character’s energy force. The unique 6.5” Energy Battle Set offers figures that respond to one to another through IR technology, allowing kids to battle their characters and perform their final attack moves to defeat their opponent. Kids can also mimic Goku’s final attack with the brand’s first role-play set, the Kamehameha Wrist Bands.
