OSNews has published an article entitled and posed the question Has the Desktop Linux Bubble Burst?

The thought of this desktop Linux burst is due to no major revisions of KDE or GNOME since 2002. It also points out the lack of future for either desktop environment with GNOME 3.0 not coming out till at least 2009 and KDE4 being far behind schedule.

Personally I don't think that means the Linux desktop bubble has burst... GNOME has had some excellent releases with GNOME 2.14/2.16 though not as nice as a complete overhaul. With Compiz / Beryl it is only powering the Linux desktop movement. Plus, when is the last time Windows had a major overhaul?
