Why are people so sure that the Star Trek spin-offs are never going to see an HD release? I mean, they were shot on film, the miniatures and most special effects were shot on film, and what little CG was used could be replaced. Granted, there's also compositing the blue-screen shots, but today's equipment can make short work of that. Read this post from a forum:

Plus, I think Pride and Prejudice was edited on video (I could be wrong), but it has a Blu release. It doesn't have Star Trek like effects, but it should show that an HD Next Generation, Deep Space 9, and Voyager are not totally out of the question. Why on earth are people so quick to assume it won't happen?
