Nope, not really. I mean I went very vague here but there has been at least one person in the thread that I read who basically outlined the story for you as far as what we know. Some people who did initial testing/playing signed NDAs and then let the cat out of the bag on reddit. It found its way here back in September 2014. I'm unsure if it would still exist here or Reddit, but the possibility exists that you could find this material on the internets somewhere.
