I have to believe that the DEV Team over at KDE; are seeing that people are either switching to different desktop environments like Gnome, and Xfce. Or staying put on Kde 3.5.. I personally know of at least 10 people who have dumped Kde4 for gnome or Xfce. When i ask them why not switch back to 3.5. They saying sooner or later KDE will abandon 3.5 for 4+ with no more updates or fixes. And they don't want to be force into accepting it. So ya i think that seeing people leave, will cause kde to take a long hard look at kde4...
