I took the liberty of editing the subject to make it clearer that (as I understand it) you refer to NanoLanguage.
We are currently working on the next edition of NanoLanguage, which will contain some improvements and updates of the standard. It will, however, still be based on Python 2.x (specifically, 2.6). Support for 3.x might be added in the future, but it is currently not part of our plans.
