To be honest, I really like the current crop of products, which I use on a day to day basis (Windows 7, Visual Studio 2010, Office 2010). And I am not a fuddy duddy because I really like the ribbon.
The thing is that Microsoft seem to be going completely mental at the moment - we already know that Windows 8 looks like a nightmare to use for actual work and Visual Studio 2012 has been sapped of all colour to the extent that it's unusable. I dread to think what they will do to office. My guess is some kind of gesture based method of making the ribbon appear or if you are one of those crazy people, not using touch; having to hover the mouse over a specific 5px section in bottom of the screen.
