I think the best thing about PyPy is that it's a modern implementation freed from the stupid architectural choices that plague CPython, and that PyPy doesn't have to get along with Guido's quirks. By that I mean things like Python 3 which did some things right but most things wrong. It's seven years since Python 3 was released and there still is no pressing need to unilaterally switch. Thus, there's no need to catch up, PyPy can continue the 2.x line while importing useful features from 3.x and possibly adding some of their own (I hope they do).
