Been a while but like they say, better late than never. I was able to build an image of centos7 on vmware studio. I'm trying to figure out if its really worth the effort.
The ui itself does not let you modify alot of the things you need you need to get the image working. For example if you open up the xml file for the profile, you would need to modify the cmd line passed down on boot so the new centos installer even starts up. Here is an example how I modified my setup.
Once you actually boot into the installler, it will complain about the kickstart file. This is because the old format wont work with centos7. It will complain it's missing %end where %pres are used. I ended up modifying it on the fly so I can get a successful template off the ground.
Anyway, I hope this helps someone else. It was a pain but it can get done.
