PyPy is self-hosted and has been for some time (a year or so?).  Maybe
you're saying that PyPy won't replace CPython for at least five years?
Could be; prediction is hard. ;)  PyPy is between 1x and 3x slower than
CPython for a lot of things, which isn't so much of a difference.  A
bigger obstacle is the availability of third-party extension modules
which currently must be re-implemented in order to be available on PyPy.
This could easily take half a decade without a full-time or otherwise
concerted effort.
