I will definitely mention that PyPy is actively working on Python 3 support
and people should help out where they can (whether it be technical or
financial) since PyPy will be faster than CPython in this regard and if you
needed a good chance to switch interpreters this would be it.

BTW, now that 3.3 is out is Antonio going to aim for 3.3 compatibility for
the initial release or stay back on 3.2?

As soon as those projects are ported we can obviously add those benchmarks.
