Yep, after receiving the email for SQL Server 2000 (hah! released ages ago) I went on a sceptical confirmation hunt and me mate Vla helped me confirm that there is a 64 bit edition in the works.
So, I went looking for some earlier releases for re-beta and came across this with the help of Vla:
We appreciate your interest in the Windows 98 Consumer Beta Preview Program, which offered customers an opportunity to "test drive" the Beta 3 version of the product before the final release.
In anticipation of the release of Windows 98, scheduled for June 25, 1998, we have stopped accepting orders for the Consumer Beta Preview. If you have already placed an order and have a question about its status, please call 888-237-6554. For more information, be sure to visit the Windows 98 Web site.
Check back regularly, we"ll be updating the site often as June 25 approaches.
damn, looks like we were late with that one :(
