James Marsters/Spike is making the move to Angel as a full-time cast member and Sarah Michelle Geller is also in talks to appear in a few episodes during sweeps. If her movie career flops like it almost assuredly will, who knows, they might get her to join permanently. Unlikely to see Giles or Xander turn up in LA, but I'm betting Willow will turn up from time to time when they need a witch and if Eliza Dushku's new series tanks Faith is a natural given her connection to Angel. They wrote Cordelia and Angel's son Connor out of the show entirely. Good thing, that was a whole "jump the shark" story arc, the show should be better without them. Glad to see Spike make the crossover there, the last 2 season of Buffy he and Anya carried the show. Hopefully he'll provide the same comic relief on Angel.
