Take this with a large grain of salt, since, if you recall, "experts" such as TV Guide's Michael Ausiello reported that Isaiah Washington was a goner last winter when the controversy over his anti-gay remarks swirled.
"I've now heard from various reliable sources that Isaiah has been taking meetings in New York and Los Angeles in search of a new job that would take place during the coming TV season, so it certainly appears that Isaiah's Grey's Anatomy days are over.
"Insiders at ABC tell me "not everyone will be coming back" to Grey's this fall, and although T.R. Knight's fate was also left hanging in the balance after the season finale, I'm hearing he's gonna be back (gotta wrap up that love triangle, not to mention his betrothed is the new chief resident)!
"But like I said, Isaiah looks to be a goner. Makes that scene of Cristina ripping the shackle off her neck while sobbing "I'm free" and the Chief's lecture to Burke that he's "disappointed" in him all the more poignant, no?"
Contrarily, Washington's publicist, Howard Bragman, said there's no indication his client won't be staying on Grey's next fall. Until we hear anything definitive from Isaiah or from ABC, consider all of this speculation.
