What we will do is drop the use of numerix internally, but the numerix module will almost certainly remain, presumably with the Numeric and numarray support removed; so numerix will still use numpy's own "oldnumeric" compatibility layer, and I expect pylab will still import from it--at least, by default. The intention is to avoid breaking things unnecessarily. I can imagine possible variations, such as using an rc param to tell pylab whether to import from plain numpy or from oldnumeric, and splitting pylab into core pylab functions (figure, show, etc.) versus the convenience all-in-one namespace (mostly from numpy); but we will take one step at a time.
