python 2.6 packages in python 3.0

[ssd]

Hi,

I usually works with packages like pyserial, numpy, mathplotlib,pyUSB, etc..

When is planned that these packages are supported in Python 3.0?

Seen this i would say that is not recommendable to use Python 3.0 at the 
moment? most of 2.6 packages are not available, not working in python 3.0.

Thanks,
Bye,
