I just noticed this on the iForum Global 2006 site; they are really playing up the "virtualization" angle:

At the Edinburgh iForum earlier this month, Citrix mentioned that Ohio (aka Citrix PS 4.5) would be shipping in 2H06 -- sounded like it would be around iForum in Orlando, which is in October.
