Jensen, has a write up on the new version of Office (2007 or version 12, which ever way you want to call it) with some screen shots.
“There are so many changes from the Beta 1 visuals that it would be hard to make a complete list, but a couple of the things you might notice right off the bat: the Quick Access Toolbar in the title bar, group titles on the bottom of groups, and the Office Button (more on that below.)”
If you’ve not need the new version of Office yet, I suggest that you look at the site. You are going to be in for a BIG change from 2003.
