Can't Wait for the New Season?
Take an Exclusive Peek into Galactica's Future

Come July, when Battlestar Galactica returns with 10 new episodes, the destinies of crew members and their spacecraft will be up in the air (and, seemingly, down for the count). Till then, here's six tantalizing tidbits:

1. After a shocker next week, someone not cut out for the job will be thrust into a commanding position.

2. "An epiphany strikes our heroes," says executive producer David Eick. They begin to understand that "It's not in their best interest to continue running," he says. Expect a major battle on the planet Kobol.

3. President Roslin's cancer-induced visions will lead her to become something of a prophet to her supporters. Like Moses, she wants to lead her flock to the promised land--in this case, Earth.

4. We'll learn why the Cylons wanted one of their own--the Sharon clone--to make a baby with a human.

5. No longer the confused wimp under the intoxicating control of Number Six, a newly energized Baltar will start gaining power and driving his own agenda.

6. Stranded on Caprica, top gun Starbuck will undergo profound changes in her kill-'em-on-sight attitude about the Cylons. For now, at least.
