Theres a new Galactica series in the works, to take place between Caprica and BSG, featuring Ensign Bill Adama in the early years of the Cylon War.
The next Star Trek movie will feature one of the following five original-series characters: Harry Mudd, Trelane, Gary Mitchell, the Talosians, or the Horta. I guess Im hoping for and/or expecting Gary Mitchell, because: Mudd is too silly, Trelane is too much like Q, the Talosians are too entangled with a specific Christopher Pike plot thread that the last film seems to have averted, and the Horta strikes me as not having, um, legs beyond its original story. (But if Abrams does use Mitchell, itll be one more case of his channeling Of Gods and Men the $150,000 libertarian fan film that featured the destruction of Vulcan and the creation of an alternate timeline stemming from the moment of Kirks birth, three years before Abrams film did all those same things.)
There might be some Star Wars sequels (CHT AICN) on the (fairly distant) horizon, but will probably not have anything to do with the Skywalker Clan and may take place as far as 100 years or 1,000 years in the Star Wars universe future, presumably to avoid conflicts with the Expanded Universe stories.
The good news is that The Hobbit will film in New Zealand after all. The bad news is that this result was achieved by government micromanaging industrial relations to keep a big corporation happy. (And no, if itd been micromanaging industrial relations to keep a big union happy I wouldnt have liked it either.)
