Oh my, what could this be? ABC's upfront was today, and Steve McPhearson - head of ABC - gave a little tidbit on Grey's. There could possibly still be a little bit more to come. Also, yes, Grey's was renewed for a fifth season, and yes, it will stay on Thursdays at 9/8c. Thanks to Kristin at E! Online.

"Grey's has got a big idea for next year that Shonda's getting ready to launch on people," says McPherson, but wouldn't go into further detail (shocker). "But the other shows we feel like are firing on really good waves, so there's no big kind of shift." (Read into that transition what you will.)

Think we'll get a hint at the "something big" in next week's finale?
