Entertainment Weekly confirms this morning that Katherine Heigl is due back on the Grey’s Anatomy set on Monday, which we pretty much gathered up based on previous reports.

As a result, it looks like Izzie will be in the final five episodes of Season Six, whereas anything beyond that is anyone's guess - yours is as good as ours, which is as good as EW's.

In other Grey’s Anatomy casting news, a second member of the Mercy West crew will not be returning next season. So look for two to be gone by the time next year begins.

Any ideas on which two? Jackson appears safe, but the rest?

We'd be surprised if Jackson weren't back next year, but his Mercy West counterparts?
