I don't think the Larians would appreciate it if the beta-testers were to leak spoilers. Some (if not most) developers have their testers sign a document to guarantee that no information about the game gets outside the building before the game hits the shelves.
You can beg, but I wouldn't count on any pre-release spoiler thread <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
