I have something. I better not say too much, in case it's not supposed to be public knowledge yet.
I recently attended Fangoria's Weekend of Horrors convention. I talked to a man who works as a technical advisor on UPN's Roswell. We talked a little about the show, and he told me that the show is not faring well on Television.
Jonathan Frakes has an idea to make a feature length film after the season, should it be canned. They want to make it a big movie - an adventure like star trek - with the original stars and some larger stars in it.
it's all a bit speculative at the moment, but none the less, found it interesting.

Thanks to Chaz and Comet for this :)
