KDE 3.4.3 release is comming shortly (official data: Oct 12). Not many new features, just bugfixes and new translations.
Also, Oct 12 is also a release date for KDE 2.5 beta 2. Final version is moved to a later date. First release candidate will come at the end of November.
It all means that also 4.0 schedule is changing (hard to say how much).
