This is what I read in the blog of one of the Debian maintainers:

I also emailed one of my upstream maintainers to ask him about the KDE 4 
version of his application and he will likely make a release soon. One of the 
goals for wheezy is remove completely KDE 3 and Qt 3. If you are maintaining 
a KDE 3 or Qt 3 based application, we are about to start annoying you about 
this! See http://wiki.debian.org/kdelibs4c2aRemoval and 
http://wiki.debian.org/qt3-x11-freeRemoval

It is interesting why they make so much effort to remove funtionality rather 
than add.
