Everyone's coming back to Grey's Anatomy

Alledgedly, according to E! Online, via TV Squad. I'm not 100% convinced - I kinda got the impression they could start off with almost a whole new cast at the end of the last series, but maybe I'm just in a "everyone's going to die or leave" kinda mood with the end of The Sopranos almost upon us.

Who's returning to Grey's Anatomy? - UPDATE - TV Squad
