Proto. Here is the only thing that matters and it isn't a PR blurb needed to fire up a message board. They have not yet solved the science, and therefore have not sent the GOO out to an independent testing lab. If and when that day comes, it won't be a PR, it will be on CNN and every other news source that follows science and technology.
Quite honestly, that's all I want them worried about and working on, without any consideration even of us investors. That is the Kobe Beef.
