Vista SP1 public beta to hit in December?

Speed boost or no, all of you clamoring for some hot Vista SP1 action will be able to get a beta-style fix in December, according to ZDNet. Apparently "selected testers" will get a release candidate in the first week of the month, with general availability to come the week after. ZDNet says the current SP1 build being tested is 17051, but it's not clear whether that's the version to be released or not. Like all things SP1, looks like we'll just have to wait and see.
