Ribbon interface in AutoCAD 2009

Found a site with screenshots of the upcoming release of AutoCAD 2009, and it looks like they've taken advantage of Microsoft making the Ribbon interface freely available to anyone! I'm so happy about this- I love the ribbon in Office 2007, though I'm interested to see how well it integrates into AutoCAD's environment.

Unlike Office, though, you have the option of customizing it extensively, as well as turning it off to go back to 'classic' AutoCAD. I hope we don't do that at work just because it's familiar...
