Seems like it's only available via an MSDN subscription now.
Also, any idea what kind of volume keys it's going to have? I've got no idea what kind of keys our Visual Studio uses on campus. They're already pre-entered on the CDs we get from Microsoft, and I'm not privy to info like that.
So yea, let me recap:
When will I be able to buy myself a copy of VS 2008 Pro?
What type of volume keys are used for it? VA, MAK, KMS?
No idea if you'll have any of this info, but I'm having a hell of a time navigating the MS website now to try and figure this out on my own.
