Possible VMWare vSphere 5 Release Date22 Jun 2011
While looking for VMA 4.1 documentation I came across this bit of time travel. VMA version 5.0 with a realease date of August 5 2011, which is just about 2 months from now. If VMA is being upgraded to 5, I would suspect vSphere would also see an update around that same time. I should note that the links for the VMA 5 docs were broken.
