So far, two release candidates of the third 'service pack' for Windows XP (SP3) have been released by Microsoft.

Is it getting closer? What's under the hood?
The overview PDF of Windows XP Service Pack 3 was posted by Microsoft late yesterday to the Microsoft Download Center and can be found here.
