The PC Magazine review of Office 2010 shows us that not much changes with the interface but new video options for Powerpoint are a welcome change, but there is also online document collaboration with web based versions of the Office 2010 suite. If you are interested in joining the Office 2010 beta you can download the full Microsoft Office 2010 Beta here.
The PC Mag article is pretty thorough and includes a screenshot difference between the old file menu and the new menu.
