Are PIL and PyGTK holding back matplotlib for Python 3?

I have a private port of PIL 1.1.7 for Python 3 that is passing all 
tests on Windows <http://www.lfd.uci.edu/~gohlke/pythonlibs/#pil> and 
works well with a couple of other third party libraries (e.g. scipy, 
biopython). Official Python 3 support is planned for PIL 1.2 
<http://mail.python.org/pipermail/image-sig/2011-January/006650.html>.

As for PyGTK, there will likely never be an official version for Python 
3: "PyGtk 2.24 will be the last release in the PyGtk series. ... New 
users wising to develop Python applications using GTK are recommended to 
use the GObject-Introspection features available in PyGObject." 
<http://mail.gnome.org/archives/gnome-announce-list/2011-February/msg00046.html>.

It seems that wxPython, in its current form, will also not be available 
for Python 3. Python 3 support is planned for the "Next Generation" 
<http://wiki.wxpython.org/TentativeRoadmap>. There is a private port of 
wxPython 2.9.x for Python 3 
<http://groups.google.com/group/wxPython-dev/browse_thread/thread/49701177b0a72c6f>.
 
I have never gotten it to run reliable.

Are there plans for matplotlib to drop Python 2.4 and 2.5? This would 
make porting to Python 3 much easier.
