I first saw this story the other day on
www.gotfuturama.com (they got it from the original ign.com news story), and like any good Futurama fan I nearly lost control of my bladder in joy. Now I hate to be a buzzkill about this, because nobody wants to see Futurama return more than me, but it has not been officially confirmed yet. Not by Matt Groening, David X. Cohen or FOX.
GotFuturama.com later edited their own news item about it to include this preface:
Due to some communication hickup within CGEF, the following had been posted without all information attached. Most importantly, our latest information from David X. Cohen is that the movie(s) have NOT been greenlit yet. So, take what Billy says as a good sign, but not neccessarily as the final word on it.
The CGEF in the quote above stands for "Can't Get Enough Futurama", which is what the site calls itself. A couple people posting messages on that site were claiming to have spoken with Matt Groening at the Comic Con convention yesterday and said that he also said the movie(s) would be done, but as of this moment, nothing official has happened. Just the fact that Billy West is talking about it is a great sign, and the fact that he's calling it a done deal makes me hopeful that it soon will be official.
