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!
Yes, it's because of the P2P issue. It certainly isn't because it made $8M on its opening weekend and $3M on its second (a 63% drop). And it totally isn't because it would likely get pulled by the theaters themselves within the next week or two.
