New release of VMware workstation (Rel 9) and updated version of Free vmplayer released
Works fine on W8 x-64 Enterprise RTM (TechNet version - not the "Leaked version").
In addition to the info in Hopachi's post
So far -- Unity has support for Full screen
USB3 works fine too -- that's what made it for me the "Must have " upgrade.
I get it free from work anyway under corporate license.
Otherwise 119 USD for upgrade.
(VMware player though Free no expiration).
