My (limited) understanding is that a lot of beamforming / MIMO techniques are limited by the power budget of the WiFi chips. So if you could use the fanciest processes, the WiFi chips could be better. I don't know if that's worth the price (everyone expects WiFi to suck 24/7), or if the process helps there, but it does sound like manufacturing technology, not math, is the limiting factor for WiFi right now.
