As you may of heard, WSv has had a name change to Hyper-V
Here are a few links:
http://www.p2vd.com/?p=224 (note: the 1st paragraph has a mistake, Hyper-V is the name, Hyper-V server is the stand-alone product mentioned later)
No one seemed to notice that 'hyper-V' was mentioned on Oct 18th on Technet, take a look here.
Do you like the name?
