Windows XP SP3 Tomorrow?
 

According to the file description notes, Microsoft will release the final version of XP SP3 on March 24, but the 5503 test build passes all Windows Genuine Advantage checks and is able to download Windows updates that previous XP SP3 builds weren't able to, which suggests that it could, in fact, be the final RTM build.

Haven't we already passed 24th March?
26th March here and no 'final release' as yet so I suspect Kevin is a little bit mixed up.
