Well, apparently they are working on a new movie, but it is VERY early in pre-production. JJ Abrams is writing/producing/directing it, or some combination of those. Probably 2008 before we will see that.
The biggest stuff is on the fan produced ST stuff, all based around TOS characters. Of course, Season 4 is in production with the New Voyages team hard at work there. At the speed they are going, they should have all 26 episodes done by the end of the century. I gotta say, the production values, especially the special effects are getting pretty good. Nice to see the support they are getting from the original cast. Walter Koenig (Chekov) just finished an episode, and George Takei (Sulu) is signed up for the next one. Lot of TOS guests seem to be showing up too
Then another group at
www.startrekofgodsandmen.com is making a web mini-series, starring Nichelle Nicholls (Uhuru) and Walter Koenig and a ton of other Star Trek stars, and directed by Tim Russ (Tuvok). Apparently, takes place in the Enterprise-B time. No clue when this will be released.
So Star Trek is alive and well, regardless of how much crap Paramount has been turning out over the last few years....
