Battlestar Galactica writer and producer Mark Verheiden posted some news about the new season today on his blog:
...I suspect the whole BATTLESTAR GALACTICA loving world knows this already, but the official Sci-Fi channel premiere date for the post-RAZOR season four is now FRIDAY, APRIL 4. Early review copies of the first two eps have gone out (I know because a friend got one) so plot details may start creeping out across the internet soon. Just to reiterate for concerned fans, the first eleven episodes of season four were shot and wrapped before the strike, and I believe the plan was always to break this part of season four into two ten episodes chunks, so... you'll get the full measure of BSG once the show begins to run.
OK fellow spirgins* out there: you know the drill...advance screeners are out, spoilers will now become rampant. Watch yourselves - especially on the skiffy forums and TWoP!
As for the rest of fandom: KNOCK YERSELVES OUT.
* SPIRGIN = spoiler virgin. The few, the proud.
