"As of this morning, the RTM version of Visual Studio 2008 (was codenamed Orcas) is available for download from the MSDN subscribers site.
BUT this may be a early or "jumped the gun" announcement, so take this with a grain of salt. MSDN Subscription Downloads is currently down, so I can't confirm it's available...
Thanks to Scott for the heads up.
Update #1 11/19/2007 @ 6:52AM (PST):
MSDN Subscribers Download is up (for me at least) and I'm downloading VS2008 now... :)
Update #2 11/19/2007 @ 7:15AM (PST):
MSDN Subscribers Download is now down again for me (and Scott too). I guess I got lucky and got in at just the right time... Glad I started the download then. :) (15% downloaded of the 3.9GB of Team Suite).
