A client has some. They were the cheapest SPARC systems available
before Sonoma, so useful when you simply needed something with
SPARC instruction set to run a legacy application.
My concern for SPARC for some years is that volumes have been way
below what I consider sustainable. Oracle and Fujitsu had done some
excellent work on the processor development, but on the other hand,
Oracle did everything they could to stop people buying them.

If ARM forges itself a base which gives significant benefits over
x86 in areas which are of interest to Illumos users, then they might
take up an ARM port again. However, I don't see this at the moment -
Joyent and Delphix are quite tied to running on x86, Nexenta and the
other ZFS storage platforms don't have anything to be gained by moving
to ARM. ARM is big in the minature low power and HPC spaces, and
Solaris/Illumos are not in those spaces. (That's not to say an
enthusiast won't port Illumos so they can run it on their tablet, but
I don't see a commercial market for a port.)
ZFS is clearly the main driver for using Solaris/Illumos over, say,
linux at the moment, and combined with the virtualisation foundations
in Solaris/Illumos, it made it worth Joyent implementing lots of Linux
compatibility in Illumos (e.g. Joyent's SmartOS virtualisation platform).
However, ZFS ports on other OS's are coming along at an astonishing
rate - particularly Linux where there are now many hundreds of
thousands of systems running ZFS (300,000 in commercial use by one
company alone), and a large number of ZFS Linux developers spread
across many companies, but all working together.
There are still some functionality gaps which limit adoption for
some use cases, but those are all being worked. I think the
functionality gaps will be gone well before the end of this year.
That would give you fully functioning ZFS on Linux/ARM, if you want
to use it on ARM, and reduces any likelyhood of porting Illumos to ARM.
