Best to let it rest. Is there a compelling reason to do more ther than just to do more?
There are pretty-much three options for more BSG:
1) Re-boot/re-imagine. Too soon since the last version.
2) Direct sequel/prequel to the RDM version. Been tried with Caprica and Blood and Chrome. Doesn't seem to have taken to well.
3) Direct continuation with BSG:TOS ala the Richard Hatch vision. Might work, if only on a nostalgia basis, but could it be sustained? Can it it be done post-BSG2003 without looking dated and silly?
