VMware is pleased to announce the general availability for VMware vSphere 4 is May 21, 2009. VMware vSphere 4 extends the previous generation VMware platform – VMware Infrastructure 3 – along three dimensions: it delivers the efficiency and performance required to run business critical applications in large scale environments, it provides uncompromised control over application service levels, and it preserves customer choice of hardware, OS, application architecture and on-premise vs. off-premise application hosting.

There you have it, General Availability this Thursday!
