Just in case anyone here is an enthusiast, it is supposed to be released on 11-16-2011. Not sure how much difference there will be, but the jump in version numbers seem to indicate something more than minor changes. The only thing that I found on it, was that it was to use a different file system from before, which sounds as though it will permit it to do something like a System Restore, and boot faster.
