Debian packages for KDE 4.4 are being worked on, just slowly and of course, keeping on with the quality you are used to. There will be also some changes that have been in some people’s TODO for long time. More here
The goal is having them in very good shape for Squeeze, that will ship with some point release of 4.4. The doubt is which point release will be: 4.4.2? 4.4.3 ? The schedule for the point releases has not been made yet, so it makes a bit harder trying to predict it.
