The "Grey's Anatomy" Cliffhanger: Your Thoughts?

So you guys know I don't watch "Grey's Anatomy," but after that cliffhanger, I figured it would be wrong not to say something...

Warning: Stop reading now if you haven't seen the "Grey's" season finale...

If you missed those last five minutes, you can see them here. And I have to admit, they were pretty good. That John Doe twist was particularly strong...



I heard an interesting theory that said Izzie is alive because she didn't get off the elevator and George is dead because he was already off. Personally, I think now that Katherine Heigl seems to be okay with sticking around that Izzie will survive, but there will be consequences to Alex violating her DNR. I think we've lost George.

Thoughts?
