I think it's completely unreasonable to ask fans to wait half a year to resume the season, and the only thing that makes it even slightly ok is the fact that the writer's strike was a big set back for them.
Just found this from TVGuide:
Ok, so they're actually in the process of filming the final scenes. Which means that there is literally no reason to push the rest of the season back until the beginning of 2009 AT THE EARLIEST, aside from Sci-Fi wanting to milk the show for all its worth, even if it means dragging it on endlessly.Speaking to TVGuide.com at a Wednesday-night screening of this week's episode, exec producer Ronald D. Moore explained that even though they are currently filming the series' final scenes, the none-too-small matters of editing, post-production and "seasonal scheduling" by Sci Fi Channel places the onset of the final slew of episodes at the start of 2009, at the earliest.
