Also, SciFi announced this about a week ago:
The cast and creators of Battlestar Galactica invite all fans and members of the Academy, guilds and Hollywood Foreign Press to a celebration of what Newsweek calls "the best show on television." The evening will include an exclusive sneak peek of the show's epic fourth season.
June 6 at 8:00 p.m.
The Cinerama Dome
6360 W. Sunset Blvd.
Los Angeles, Calif.
Seating is limited to the first 500 attendees; special seating will be available for Academy, Hollywood Foreign Press and guild members.
ETA: Apparently Jamie will be appearing at the event. :)
