Intel's wearables push always seemed more like a PR stunt than an actual, thought-through business tactic. They put a great deal of effort into stuff like Arduino support and sponsoring BMX championships, a TV show (America's Greatest Makers), conceptual clothing lines, etc but apparently people who actually wanted to use their hardware in products had trouble getting support or chips and the specs just didn't seem to stand up (when they were available at all).
It was, and to appease investors that they are doing something about new markets after missing mobile. No one in their right mind would choose Intel as the platform for a wearable. The microcontroller companies: ST, NXP, Freescale, etc have been deeply embedded there for decades.
