It's called dollhouse. You can find updated info on the unoriginally named dollhouse.
Depending on the writer's strike it will probably air beginning Fall 2008. Fox didn't just order a pilot, they ordered 7 episodes. wooohooo. It's about a group of people who are programmed as needed to fullfill the needs/fantasies of those who can afford them. after their assignments their minds are wiped clean so they have no recollection of what they've done, nor do they know anything about themselves. When they are not on assignment they live in the lab otherwise know as the dollhouse. :D Not only is it a Whedon creation, but another fabulous whedonverse writer is already onboard, and the show is staring whedonverse alum eliza dushku.
And I would LOVE for him to make another firefly movie as well, but I'm pretty sure that is not going to happen :(
So you see, I am going to badly need more icon space...
