I just ran across this yesterday and upgraded to it today. It is the Vegas Pro Suite upgrade for us Vegas 12 users. The great thing about this is that it incorporates the Hitfilm Ultimate 2 effects and compositing software engine as a plugin, or it can be used as a standalone system. If you will look at the features, it can even do 2D and 3D motion tracking and much, much more. This is exactly what I have been waiting for, so that I can move on into mixing animation models with live action. I'm just posting it here because it is a great product and I'm very excited to begin using it and wanted to share the find.
