"so is there already a binary for qt/pyqt/eric3 available or when can i excpect qt4 to be released? "
I think that pyqt4 is going to be a long way off, obviously further away than qt4. i have compiled qt 3.3.3/pyqt 3.1.3 using mingw/vcc6 for windows using the instructions i linked to in my previous post, both for python 2.3 and 2.4, when the kde-cygwin guys finish porting qt 3.3.4, i'm going to have a go at pyqt 3.1.4 -- http://mail.python.org/mailman/listinfo/python-list
