This is an excellent observation. I have heard some reports of Group Policy issues from other versions of Windows Server not necessarily being applied correctly to WIndows 8. Given the scope of the changes in Windows 8, this isn't particularly surprising.
I'm going to do some research on this topic. It's definitely something that needs to be considered.
That said, I have had the chance to work with WIndows Server 2012 and if anyone is considering upgrading, just do it. WS2012 is rock solid.
