According to IGN, they have listed the official Roster for WWE Smackdown vs. Raw 2008. So far the roster is announced for the Playstation 3, Nintendo DS and PSP versions. I am assuming the PS3 Roster is the same as the Wii, 360, and Ps2's Roster, but I will confirm that once I find out. Anyways, here is the Roster: Playable Wrestlers: Batista Bobby Lashley Carlito Chavo Guerrero Chris Masters CM Punk Edge Elijah Burke Finlay Gregory Helms Hardcore Holly Jeff Hardy John Cena Johnny Nitro JTG Kane Kenny Dykstra King Booker Mark Henry Matt Hardy Marcus Cor Von Mr. Kennedy Montel Vontavious Porter Randy Orton Rey Mysterio Ric Flair1 The Sandman Shad Gaspard Shawn Michaels Snitsky The Great Khali Tommy Dreamer Triple H Umaga The Undertaker William Regal Divas: Ashley Massaro Candice Michelle Jillian Hall Kelly Kelly Maria Melina Michelle McCool Legends: Bret "the Hitman" Hart Eddie Guerrero (PSP Exclusive) Jim Neidhart (PSP Exclusive) Rick Rude The Rock Rowdy Roddy Piper Sabu Sgt.
