Today (07-dec-2007) at the Dutch VMUG Event, Jeremy van Doorn (Systems Engineer Manager Benelux at VMware) stated that the new version of ESX and Virtual Center (2.5) will definitely be available this year (2007).
That it would be available soon was expected because I was noticed that the testing and assurance department approved it and together with that the Beta was closed by VMware:
From Eric Sloof’s website:
"VMware closed the beta : Thank you for your active participation in the beta program for the new release of VMware Infrastructure 3 comprising VMware ESX Server 3.5 and VirtualCenter 2.5. We are pleased to announce that this new release will be generally available by mid-December, 2007.
I’m not sure the following links will lead to the final version (there isn’t a GA yet !!!). "
Update: I removed the links because the downloadable version was not the definitive build.
