There's no beta for Workstation at this moment.
The people who know any details cannot tell due to the NDA.
I think you are also aware of the no comment policy at VMware.
Eg: "It is VMware policy not to comment on future features or policies, so there won't be an official answer unless marketing decides different (which usually it does not)"
So AKAIK we will have to wait a bit longer to see what is coming up.
