Well, I would love to download it but the URL is reporting HTTP 500 errors. Oh well.
In a letter just sent to testers, "Final testing is complete and at 10:08am this morning we signed off on build 2180 as Windows XP Service Pack 2, releasing it to manufacturing. The final build will be available to beta sites immediately at http://windowsbeta.microsoft.com/download/dl3.asp. You will find both English and German versions there, Japanese will follow early next week. Next week the service pack will be available on the Microsoft Download Center for general download. In the interim we're making the update available to you via the beta web site. If you are running RC2, or any other build released to beta sites, we invite you to turn on Automatic Updates, and starting on August 10th your system will automatically download the express version of Windows XP SP2. For typical home users this is about a 75 MB download; for those on RC2 it should be less than 30 MB. "
