The future of Bones is uncertain on a few levels. First, it has yet to be picked up for a seventh season. Secondly, if it is, Emily Deschanel's pregnancy could cut it short. That's just one of the options the show's executive producer Hart Hanson revealed in a conference call Monday, according to TVLine.

The options for the show's possible next season include: halting production for Deschanel's maternity leave, starting late and delivering a shorter season (16 or 18 episodes as opposed to the usual 22) or filming episodes, in which Deschanel's Dr. Temperance "Bones" Brennan character does not appear.

Adding to the uncertainty is the lack of seventh-season scripts stemming from the fact that the show has yet to be picked up. However, Hanson says Bones' future will be certain by May 15, adding optimistically: "I'm very confident that we will come to a deal."
