There was a period centered around the late '90s where new architectures were a dime a dozen, as access to fabs opened up, and small companies with an idea hoped to become the next Intel.

Anyway, ESP32-C3 is RISC-V, and I suspect they won't do any more new Xtensa cores.

They've explicitly stated it's all RISC-V from here on out.

Yes, the announcement of the ESP32-P4 certainly makes it look that way.
