What's needed, and possible, today, is a competitive and relatively simple AVR or ARM-M0/M3/M4 replacement (with I2S). Such a chip is likely to receive stellar support from the maker-community. My gut feeling says that such a chip is likely to come from Samsung, but NXP and Expressif are also likely candidates. All are RISC-V members. Anything more complex should wait until the specs are complete.
