Keep the licensing model of Windows Server 2016 as in 2012
The WS2012 licensing model with absolutely the same features in Standard and Datacenter Editions was the greatest thing. Virtualization rights was the only thing to think about - no headache about what is supported in which edition, what I should install, will it work etc. Please keep it like this in Windows Server 2016.
simplify licensing and differentiate on usage capacity, not features. Dang it guys, I'm so disappointed. Initial licensing for 2012 R2 was the best model you've had so far. Do more of that not less!

Unfortunately, it appears there are already some shifts happening. 2012 R2 added AVMA (which made sense given the licensing strategy), but now 2016 looks to be adding actual feature differentiation between the editions - Storage Replica is only in Datacenter, not Standard (see http://blogs.technet.com/b/filecab/archive/2015/06/03/the-storage-replica-video-series-storage-replica-with-rdma-and-25km-fiber-in-windows-server-2016-technical-preview-2.aspx)
