With Workstation 11 we have seen the integration with vCloud Air: uploading, running, and viewing virtual machines from the interface, to make a kind of hybrid cloud between your workstation and vCloud Air.
With this new release VMWare want to give up a gear:
VMware vCloud® Air™ Incentive Program – To help users get familiar with the benefits of cloud computing, VMware Workstation 12 Pro customers are eligible to receive $600 in vCloud Air service credit to use for up to 6 months – twice the standard VMware vCloud Air sign-up offer.
Other cool things are the ability to run Windows 10 and the last release of important OS (CentoOS, Ubuntu, ...) and the support for DirectX 10 and OpenGL 3.3.
