Check out this article to read about the Mstie Crew at the San Francisco Sketch Fest 2004.
It’s got a lot of cool little bits, including a RealAudio clip of Kevin Murphy dogging some 2003 movies.
At the end (very interesting, this), they intimate that MST3K may return in one form or another in a couple of years.

Finally, the Sklar brothers asked Mike, Kevin and Bill if there was a chance that MST3K would ever return. “I’m sure it will,” said Kevin. “Look at Star Trek. I think after it’s gone for a few years, people will want it to come back. But I don’t know in what form it will be.”
Added Bill, “In a way, it’s a good thing the show’s ending its run on Sci-Fi. After watching the same episodes being repeated for the eighteenth time, it’s worn out its welcome. Give the show a little rest, and eventually people will want to see it return.”

Interesting indeed. One can hope.
