At this point in time, KDE4 is still pretty crappy and the same is true for our KDE4 packages (or at least last time I tried them). They are available for the adventurous, read more about it here:
http://www.vectorlinux.com/forum2/index.php?topic=5716.0I don't think packages will be in the repository any time soon, unless KDE developers make a
huge leap forward.
If you really like KDE3 and think 4 will be the same but better, you'd better stick with 3 for now. KDE4 can't do half the things it's older sibling can do. The only thing it can do that KDE3 can't, is make more eyecandy and gobble up even more RAM
