Paging the cast of Grey's Anatomy... get back on set, STAT!

With a tentative agreement between striking writers and Hollywood moguls expected to be announced sometime this week, TV Guide's Michael Ausiello reports that production on the show is expected to resume in early March!

The current plan is to shoot four or five new Grey's Anatomy episodes to complete Season 4. Those episodes would air in April and/or May.

A similar scenario is expected to play out at other established ABC hits, such as Desperate Housewives, Ugly Betty and Brothers & Sisters.

According to reports, Season 4 of Grey's Anatomy isn't done yet!

Conversely, freshman shows that already received full-season pickups (such as Pushing Daisies, Dirty Sexy Money, Samantha Who?) will likely restart their production schedules over the summer ahead of a fall relaunch.

Expect a similar pattern to play out at CBS, NBC and Fox: The more established shows returning in the spring; newer ones held back until this fall. The fate of heavily serialized shows like Lost, Heroes and 24 remains unclear.

Meanwhile, sources close to the talks say the WGA deal is close to the DGA deal, with a few exceptions â€" one of which is a "major breakthrough."

In any case, how happy are you to hear this Grey's Anatomy news?
