Funny story about the Myo. It was a promising device and seemed to me like it had great niche applications (such as medical). Founders weren't interested in that I guess and moved to smart glasses. Last summer they sold the patents for Myo to a company called CTRL Labs for about $20M. In the fall Facebook snatched up CTRL Labs for $500M - $1B, and their product description was basically that of the Myo.
