I would be very surprised if they didn't do an RC.
Can't imagine it going from Beta 2 > RTM.
I haven't heard anything about RC yet, but I'm sure it will happen (October time maybe?)
Internal milestones are different than the public releases. Ofcourse they'll have a RC (maybe more than one), but given that Beta 2 was feature complete and is very stable, I don't think there is a need for another public release before the RTM. Their testing
efforts are probably well spent on the RTM and getting thru their internal milestones.
