I don't know what else to say. I'm speechless. This app looks great! If it operates half as good as it looks its a winner. My biggest gripe with Smoke was the outdated, complex, and cumbersome UI. I'm especially glad to see that they didn't reduce functionality. All of the things that made Smoke great are still in there, just packaged and displayed in a much more editor-centric way.
Oh, and don't miss what type of computer they're showing Smoke 2013 on. And yes, that's an intentional move by Autodesk.
