Also, RISC-V hasn't been bought, litigated, and buried. Alpha is great, but we're about as likely to get new implementations of it at this point as we are of the 6809 or v20.

RISC-V's future is looking better and better. Who knows? Maybe TSMC or Samsung or one of the smaller fabs puts out a multicore version on a fairly modern process node and gets a multi-player motherboard market built in Taipei, Seoul, and Shenzen. It could be a player in laptops, desktops, tablets, and mobile rather than just embedded and SBCs. It could even be done without a premium going to Intel, AMD, ARM, nVidia, TI, Freescale, or IBM. The possibilities are exciting, because every time I hear about this ISA and its implementations it's better news.
