Yeah, most likely. The reason is simple: folks want a desktop that doesn't fight them, has fast window switching, navigation, and task management... and then stays out of the way.
GNOME knows best, though, right? pArAdIgM sHiFt (tm)! What is a desktop? Hide everything!
For all it's faults, KDE is much more usable. Xfce is great, too. They treat the desktop/laptop computer as exactly that -- not some strange hybrid between traditional desktops, mobile UI, and kiosk GUIs.
