There has been a decent amount of projects recently. Andes Announced 1.2 GHz CPUs made on 28nm die, and a Chinese company are taking orders for a 400MHz dual-core AI chip. SiFive at the start of the year did start selling HiFive Unleashed, but it is very expensive.

The Berkeley processor is mostly a research CPU for FPGAs. I would however love to see it on actual silicon.

At a guess i'd say it will be a few years until we see RISC-V popping up in more places.
