Chyler Leigh and Kim Raver are out. Eric Dane will soon join them. Gaius Charles and Camilla Luddington are in.

Indeed, the hallways of Seattle Grace on Grey's Anatomy Season 9 will look VERY different than in past years. But ABC Entertainment President Paul Lee isn't too worried. He has enormous faith in Shonda Rhimes.

“If you look at what Shonda’s done… she has maintained the critical dynamic behind that show, the creative dynamism, for such a long time," Lee told reporters today at ABC's session of the Television Critics Association press tour. "And I love to see her taking risks and reinventing the show every year.”

Will there be any more significant pieces of casting news announced?

"I think you’ve seen the major moves," Lee said, adding that he's "excited" about where Rhimes and Grey's are going after such an intense season finale.

Hear that, fans? You can finally take a breath. Until the September 27 premiere, of course.
