No. They did create Sound Forge for Mac and Spectral Layers runs on Mac but not Movie Studio or Vegas Pro. One can only hope.

I've been running Vegas Pro in a Windows 7 virtual machine with VMware Fusion on my Mac Pro and it works well. You can also use Parallels Desktop. I have a Bootcamp partition for the few Windows programs that I still use on my Mac and Vegas Pro is one of them. At that point it's running natively.

So you certainly could run Movie Studio on an iMac if you really wanted to, You just need Fusion, or Parallels, or Bootcamp.
