Except of retro computing (: there are MPC Freescale and TI 6502 compatible microcontrollers on the market.
Also, there Freescale Coldfire microcontrollers with my favourite (within oldies) 68000 architecture.
So may be there are some application for the non C software on those platforms. However those developers most likely won't consider Oberon and are not members of this list (:

Very interesting indeed.
I mostly use AVR chips for my hobby projects, with custom made boards (never used arduino).
For some of them I prefer PICs.
I do not prefer PICs because usual PICs are accumlator based (like old 6502) and have complicated RAM access. However even cheap models may have hardware usb.
Anyway I am definitely far from being an expert in eletronics and mcus.

Some people currently use cheap chips instead of hardware logical elements. It may be cheaper to use PIC instead of a couple of AND elements.
PLC's often contain AVR chips inside.

I honestly do not have any idea whether 8bit, or even mcus will exist in the future, especially if fpga become comparably cheap.
However, I hope so (:
Sincerely,
