I just got the confirmation from the Cisco representative as the Nexus 1000V will be bundle on the Cisco UCS as FOC if the customers who deploy the virtualization VMware vSphere 4 with  Cisco UCS platform. It will definitely be helpful and encourage more users to be adopted on nexus 1000V implementation in the Virtual Infrastructure when the VMware vSphere 4 are deploying on Cisco UCS platform. If you are running the VMware vSphere 4 with others server vendor, the Nexus 1000V will be an extra features with additional cost.
