If the new build is out and playable by this weekend ~ 11/5 then there could be some weekend invites for the 12th. Without a doubt there should be a huge beta invite before or the weekend of Thanksgiving.
It looks to be an "open beta" of sorts and there going to invite a buttload of folks and everyone is going to have access to the same forums to try to get some last minute feedback and stress testing in.

Can't go into details, but you can skip all the dialogue and cutscenes and still make the correct ds/ls choice to go your destined path.
