But that compatibility is not achieved with emulation, right?
The PS6 can hopefully keep compatibility with PS5 and PS4 in a similar way. Unless we are nearing some sort of ARM horizon for consoles, that is.
RISC-V makes the most sense. It means they wouldn't be locked into one CPU supplier. Requiring a GPU based on RISC-V (or a separate open GPU ISA) could further insulate them from the current AMD lock-in.

The documents accidentally leaked from the FTC vs. Microsoft trial revealed that Microsoft was at least considering switching to an ARM CPU with the next Xbox generation, but they hadn't decided yet at the time those documents were written. Either way they would still use an AMD GPU, so it would be AMD+AMD or ARM+AMD.
Microsoft has been working on perfecting x86 emulation on ATM so it's not far fetched to think they could still keep backwards compatibility.
