Well according to the Q&As from other boards Han Torture Rack and Hermi Odle are confirmed for this year. They said at least one of Arleil Schous, Brainiac, F'u Man-Chu, & Bom Vimdin will come in '08. My money's on Bom Vimdim; he was in a fan choice poll once. Brainiac has probably the secod best shot. I doubt they'd do another wolfman. I don't know who F'u Man-Chu is.
Now if they would just tell us why Biggs won't have his cape!
