Probably too soon to tell
I remember similar reports for (pretty much) EVERY Windows O/S release ever. If you use Win8 in Desktop mode, you essentially have Windows 7 for all pragmatic purposes. Metro will be choice when you're on a tablet, Desktop mode when you're at your desk. So, I think it will all depend upon the needs of the users. I know I'm ramping up to deploy it on MY computer, just because I want to be able to share elements of my desktop with a Surface Pro tablet once it releases in 2013 (an experience that I can't quite capture with an iPad). But for most of my organization, it probably will be a non-issue. We'll cut over to Windows 8 (or 9) as we upgrade/replace machines.
