The news Battlestar Galactica's final season won't air until April 2008 in the US (likely to be June/July in the UK) isn't good. But I'm getting increasingly psyched for the prequel special Razor -- released late-November in the US (December in the UK, hopefully.)
Also, if you've been missing them, special mini-episodes ("Razor Flashbacks") have been circulating from the Sci-Fi Channel website onto YouTube recently. Now, I know -- usually such episodes play like deleted scenes and filler -- but the Razor Flashbacks are really high-quality stuff!
So good in fact, that I'm pretty sure they must be from the actual show itself -- the effects are amazing and very ambitious for TV.
So, if you've yet to see them:
Razor Flashback 1, Razor Flashback 2, Razor Flashback 3 and Razor Flashback 4.
Original Cylons and old-style Raiders :)
