Yup. She was supposed to come back for the last 5 episodes of season 6 (presumably so Shonda could have her killed off, but that's just guessing). However, she didn't show up and asked to be let go from her contract, which happened. I read somewhere Shonda wanted her to return for season 7 to wrap up her story, but Heigl declined. Then not so long ago, Heigl expressed interest in returning to wrap it up, but Shonda has made it clear she's done with her and doesn't want Izzie back. Though, it's rather obvious she's actually done with Katherine, and not so much Izzie. Too bad when behind the scenes drama interferes with the storylines.
