"Grey's Anatomy": Who Might Be Leaving?

In the midst of all the excitement over ABC's new shows, I forgot to point out a bit of gossip that sprung up around one of the old ones: "Grey's Anatomy." There have been rumors floating around for a while now that someone — maybe TR Knight, maybe Isaiah Washington, maybe Sara Ramirez — could be leaving the show at the end of the season. The Knight and Washington rumors date back to the on-set scandal last fall, while Ramirez's departure would pave the way for George and Izzie to be together — and when a reporter recently asked Ramirez if she'd be back, she responded with a "maybe."

Before ABC's schedule presentation, reporters asked ABC President Steve McPherson if someone would indeed be leaving, and his responses were less than reassuring; according to E!, the answers "ranged from 'at this point, nothing's been decided' to 'The show will return intact next season' to 'Most of the cast will return.'" Yikes!

So, do you think someone's really leaving? And if so, which cast member will it be?
