From Billy West himself (billywest.com), there will be 4 feature length straight to DVD Futurama movies made. No word on a release date but they start recording in July or August. It may not be a return to television, but I'll gladly take it!
I've seen that the copyright on the movie was 1980. I prefer the theory that the grad students running the experiments are now Bluebeard and the lady on the boat. Besides, didn't someone (Jack? Locke?)
