How does it changed for virtualization? As you can see the Enterprise edition is no more available (according to the FAQ: Enterprise edition will be retired as part of the Windows Server 2012 release) so the right solutions become the Datacenter edition. This is already usual today for medium and large environment, but for some small environment the Enterprise edition was a possible choice to reduce the cost. Standard now provide 2 instance for virtualization (but are not the 4 of the Enterprise).
