Just saw this @ good old Neowin.net.

Microsoft have got their thumbs out from wherever they were and released what they are calling Pre RC SP3 for Windows 2000. This would indicate at least a Release Candidate before release is expected in early summer (June we thought, but hey!).

It simply says: NEWS May 28th, 2002: We are pleased to release the SP3 Release Candidate (RC).
