There already are shipping, commercial RISC-V cores. The end-products are things like cameras though, so they're not very likely to make the tech blog rounds.
The issue though is that nobody HAS to tell us they used RISC-V (that's part of the beauty of it). For small micro-controller type cores, the decision is made by some engineer to go with RISC-V instead of rolling his own ISA ($ and time are too tight to go external for a simple micro-controller), but that doesn't mean he has the power to publicly announce to the world what tools and IP his company uses in its products.
Anyways, we're trying to get more people to open up so we can help make a stronger case for RISC-V by using more success stories from industry.
