The big upgrade, from a functional standpoint, is that it supports and manages Live Migration. Live Migration is the ability to move a running virtual machine (VM) from one physical server to another, with no downtime. Live Migration was a key upgrade for the Windows 2008 R2 beta. Without it, Microsoft can't really compete with its main rival, VMware, which has had its version of Live Migration, called vMotion, available for years.
