Brief video tutorial on using the touchscreen and Apple's Majikmouse is on MacRumours.com
Is it faked? I think so. Autodesk alphas and betas are in English, with other languages coming out around FCS. The Getting Started dialog box contains mostly placeholders, which I find odd, since it is done in Flash, thus OS-independent. The screen grabs are easily faked. The 3D rotation in the video is very rough, and not something Autodesk would want to show off. In the video, the multitouch motions for the screen differ from those used by the Magicmouse, which is illogical.
