"New Cast Joins Clone
New voice actors will join the cast of the Star Wars: Clone Wars "microseries," the official Homing Beacon newsletter reported. The second season of 10 episodes will premiere March 26 on the official Star Wars Web site and on the Cartoon Network.
The new cast will include Kevin Michael Richardson (K'Kruhk), Daran Norris (Ki-Adi-Mundi and Daakman Barrek), Cree Summer (Luminara Unduli), Tatyana Yassukovich (Barriss Offee) and Futurama's John DiMaggio (Bender) as Clone Wars' villainous Gen. Grievous.
Returning cast members include Mat Lucas (Anakin Skywalker), James Arnold Taylor (Obi-Wan Kenobi), Anthony Daniels (C-3PO), Tom Kane (Yoda) and Grey De Lisle (Padmé Amidala, Asajj Ventress and Shaak Ti)."
The idea of Bender and Grievous changes any preconception I had of the character, but I really hope they some new toys; animated versions of these characters as well as regular Clone Wars versions, though I guess if they were, we'd know by now, wouldn't we?
