It's the fact it's Glen Larson again that has me interested (he lost TV rights to his creation, but kept the movie rights). A Galactica more in line with the original ideas would be interesting: Cylons who are actual aliens, for example. Their description in the novel, credited to both Larson and Robert Thurston:

“As far as Apollo could see there were Cylon warships, with their odd curves and arclike limbs. In one of the ships he could see the usual triad that composed a Cylon fighting crew. Two helmeted pilots sat side by side. Their tubular shaped helmets covered what Apollo knew from a closeup examination of Cylon corpses to be many-eyed creatures with heads that apparently could alter shape at will. In the center of the helmet was a long but narrow aperture from which emerged fine concentrated beams of light. No human had ever discovered whether the light was generated by the Cylons themselves or was some facet of the helmet's technology. ”

I think the reasoning is a) due to the reboot, the name is now known again, and b) the reboot burned itself out. So, if you're going to take advantage of the franchise, you start over again.

I recently read Heinlein's "The Moon Is A Harsh Mistress". It's a really interesting tale of a luna penal colony trying to gain it's independence. Well worth a read. I mentioned this to my neighbour who loves Heinlein who wouldn't let me leave without a copy of Stranger In A Strange Land
