Any information on future CPU's with support for hardware accelerated PQC algorithms? Will all my old devices become slow when PQC is the norm and encrypted communication is no longer hardware accelerated?

Only the asymmetric portion of the cryptography (which is only used in the handshake) will need to use PQC algorithms. Symmetric crypto algorithms (AES/ChaCha20/SHA-*), which are used after the handshake, are not as badly affected by quantum computing so they're not being replaced in the immediate term. I'm pretty sure that general purpose CPUs do not have hardware acceleration for the asymmetric crypto anyways.
you don't really need that tbh. you can get pretty good speedups using standard (vector) intrinsics. the new algorithms are (mostly) modular linear algebra (+ some concept of "noise").
