Yes, I'm well aware of those threads (and to be clear, only the first and third threads you posted are of any relevance ) There have been rumors for ages about the possibility of a Futurama movie or the show returning. I'm not sure what the first thread you pointed to was talking about (most likely the confirmation of the movie), but the third one was Billy West telling us that they're going to make a direct-to-DVD movie. What I posted is something completely different. Billy West confirmed that there is going to be 26 brand new episodes of Futurama that will air on TV. He just confirmed it this weekend for the first time. It's something completely seperate from the reports of a Futurama movie coming.
Looks like the celebrations were premature. Slashdot just linked to another thread in Billy West's forum where he posted this:- Full thread here - linky
