Well they are even giving the MSP designation to ARM cpus now (MSP432 is
based on Cortex M4).  Of course they'll keep shipping existing 430
models as long as people keep buying them, so my question is more about
whether there will keep being new designs.  I do get the impression that
there aren't that many new design wins for the 430.  There is apparently
some process limitation that prevents them from making ARMs with FRAM
but maybe they'll get around that somehow.

Well I mentioned a few niches, but as you say, they are niches.  I do
think designers care about future compatibility and capabilities as well
as the short-term price, and I dunno that the 430's are really cheaper
than ARMs for comparable parts, especially at the higher end.

I'm also awed by the low price of some of the Espressif wifi parts
(ESP8266 and so on).  They use a MIPS-inspired 32-bit instruction set
roughly comparable to a Cortex M3, not binary compatible but there's a
GCC toolchain for it.  I don't think they have any process advantages or
anything like that, so all I can think of is that they're lowering costs
by not having to pay ARM royalties.

Take a look at wemos.cc sometime -- their D1 wifi board is a favorite in
some circles around here.  It's crazy cheap, quite powerful, and runs
Lua (NodeMCU) and Micropython as well as the usual C stuff.
