Windows 8.1 Enterprise

Thanks for asking, I was kinda wondering about this myself. My plan is to use Enterprise until there's more news on the activation front (KMS6, the "real" RTM, Cody, etc.)
Even if I have to reinstall every week (which only takes 10-15 minutes thanks to Win8PESE, JFX's WinNTSetup and my Postinstall thingy), it would still take up less time than spending hours and hours figuring out how to activate etc. Well, I'll do that as well, but you catch my drift...

 

Still? I remember 8 vanilla having an unlimited grace period. I'd expect the same with 8.1.
