Care to point to the source of this claim? Two main suppliers of MIPS
silicon in this century are Microchip and Cavium (now owned by Marvell).

According to my understanding Microchip's MIPS-based PIC32 line was
never as popular as their other offerings.

In case of Marvell, I no longer see MIPS-based Octeon III chips in the
product section of their Web site. Which, I'd guess, means that in order
to buy one you has to be an existing customer.  Since the market that
Octeon III was playing in, is rather dynamic, I don't expect that those
existing customers buy very old chips in tens of millions. Likely not
even in single-digit millions.

Sort of.
And majority of my FPGA designs run Nios2 soft cores that are also
'sort of MIPS'. But they are *not* MIPS.
