It will only happen if a company decides to try and be the next raspberry pi chip (or as a by-product like the OG broadcom chip from the Pi1). The actual chip designs, I think, are already there in terms of getting a high-performance risc-v chip built, but currently the market and tech stack is still getting they so we are still at the scaled-down-test phase in the high end market. FWIW though I don't see much reason to care about the ISA of the CPU beyond it being RISC, chances are it'll still be full of all kinds of closed source crap like the Pi.
