Can't wait until Whedon brings out his next project. I'm sure I'll love that as well.
Last year, I was hearing in some of Lynda Carter fangroups that he was set to direct the upcoming Wonder Woman movie, with numerous disputes over who should play the role, as well as some disapproval over rumors about getting away from the "Lynda costume".

Wonder Woman has been officially canned.
Whedon is going back to TV for a series called The Doll House with Eliza Dushku. I think she plays an agent of some kind of Manchurian Candidate style group of assassins.
He's also been working on a feature called Goners for what seems like, well, ever. As far as I know it's still on the table.
I'm just happy to take in anything with his name attached to it. His episodes of The Office have been some of my favorites of the entire series.
