[Aegon the Unworthy]

In the podcast for the last episode RDM says there is a definite conclusion and did hint that this is the last season.

For the record BSGs ratings werent that good. The audience was reasonably broad but it lost a third of its numbers to TIVO/DirectTV. Advertisers dont pay for those numbers because most of us fast forward through the commercial. Where BSG rocked the house was critical acclaim, received praise and what not and raised the prestige of the network. Without the critics and peer reviews the network would have cut the show.

Dont think Im smart, this is all in the podcast I mentioned above.
