AFAIK, there is no concrete roadmap towards supporting SciPy on top of
PyPy. Currently, PyPy is getting its own implementation of NumPy-like
arrays, but there is currently no interaction with anything in the SciPy
world outside of those. Given the shear size of SciPy, reimplementing it on
top of numpypy is unrealistic.
That being said, it's quite possible to fire up CPython from PyPy (or vice
versa) and interact with that, if you really need both PyPy and SciPy. It
even seems to be supported through multiprocessing. I find that pretty cool.
