In addition to the previously reported Windows Vista SP1 drop to testers, Microsoft has just recently (few days ago) dropped a copy of Windows XP Service Pack 3 in the lap of the same small group of testers. Coming in at less than 350MB, the service pack includes fixes for over 900 reported problems, some of which have already been resolved with post-Service Pack 2 hotfixes.
