Q. What went wrong with the RTL?
A. I didn't get a direct answer with this other than delays were made to make better decisions about what direction the company would take due to competition and bitcoin price.
The difficulty rise was too rapid and manufacturers started offering very efficient 28nm products at $3/GH - Ken realised Nextreme chips were too expensive to manufacture and too inefficient on power. The right decision was to switch to Easicopy, and this is the decision I believe Ken made. I've been saying it for a while now, quote me on it later.
If this is the case, people should be extremely impressed with the companies ability to "turn it up", and ken's guts to take this step despite the fallout we're seeing on the forums.
