The Matsushita chip is used in the recently announced Solbourne workstation,
and is not available to other vendors.  There are some indications it might
be put on the market as a chip; anyone have any knowledge of Solbourne/
Matsushita's plans in this regard?

This is the only SPARC chip now in production that has on-chip cache, mmu,
or floating-point -- and it has all three.

Note that this is 64-bit only in that it has 64-bit buses; it is NOT a
64-bit extension to the architecture.  That won't come for a year or more.
(Probably more -- maybe several years.)
