I think there will more than likely be another special rather than another series. I doubt Dave could ever fund a series, certainly not in a credit crunch. I think these would be good centered around the search for Kochanski. Like a quest across the galaxy, could mostly take place on Starbug and outdoor sets made to look like moons / whatever, so could be made to a moderate budget, perhaps a bit higher than last time, perhaps even borrowing ideas from the lost Series VII episode. Kochanski could have been captured and is now for sale at a simulant slave market or something. Certainly the way the Shepperton street turned into a chinatown market turned out, I can see it being done on peanuts. This for me would be a good Series VI style episode with a lot of chance for dialouge. I also think locking the four into Starbug's cockpit one more time for some epic dialogue based action would be good. The Starbug set is so good because it effectively imprisions the cast into a situation, whereas on Red Dwarf they tend to wander off and do their own thing.
