Mike Ausiello at TVGuide.com seems to have grabbed what could be ABC's new fall schedule, placing Private Practice on Wednesdays at 9 and Grey's in the same spot [shock shock], with a new show premiering after - Football Wives. Check it out:

WEDNESDAY
8 - Pushing Daisies
9 - Private Practice
10 - October Road

THURSDAY
8 - Ugly Betty
9 - Grey's Anatomy
10 - Football Wives

We'll bring you the confirmed schedule this Tuesday. Stay tuned for more!
UPDATE: Rumors are flying that this schedule is completely and utterly wrong...but there's no way to be sure until this Tuesday, so stay tuned!

Most likely, Grey's Anatomy will not be affected by anything revealed this Tuesday, May 15 at ABC's fall upfronts. We already know it has been renewed for a fourth season, but not the number of episodes or the timeslot. Most likely, Grey's has been renewed for 22 or 23 episodes and will be staying in its same timeslot of 9PM on Thursdays. However, we'll also find out if ABC picks up Private Practice, the official title of the show (if that isn't it), and the timeslot for that. And we will also find out if the surrounding shows will be the same - Ugly Betty right before and Men in Trees right after. But the most interesting thing we will find out? We'll find out if Grey's will be going up against NBC's hit The Office, as there are rumors flying that the show will be expanding to an hour and if it is, well, then it's probably going to need a new timeslot. Whether or not that will be at 9PM on Thursdays we don't know yet, but we will find that out on Monday, May 14. So stay tuned! We'll bring you all the info from ABC's fall upfronts Tuesday afternoon!

Flying around the web today is a supposed airing schedule for the rest of Grey's current season. It's obviously not completely correct (ie My Favorite Mistake is one episode, but two hours, and therefore counted as two seperate episodes - but they're most likely airing at the same time unlike Six Days), but, here it is anyways, just so you can see it and plan accordingly. And, according to this, the season finale is set for May 17. Mark your calendars (but only in pencil)!

March 15: Episode 318 Scars and Souvenirs
March 22: Episode 319 My Favorite Mistake
March 29: rerun
April 5: rerun
April 12: Special Clip Show Every Moment Counts
April 19: Episode 320 Time After Time
April 26: Episode 321 Desire
May 3: Episode 322-323 [spin-off episode]
May 10: Episode 324
May 17: Episode 325 (Season Finale)
