I think the situation is more fluid than holding AE to a statement made prior to much of what is now available (to them), so that statement if it was in fact made, is to be taken more lightly at this point. While I believe that is and will be the intent,(buy out) AE cannot let his actions be dictated by that intent, or the value of the company will be diminished by buyers who may percieve a weak hand.
I also think that the response and demand from the NDA's in June and prior has been such that it may have caused this board to reflect on developing a unique process to achieve purity in grade and optimal graphitic quality economicly.
IMO, the end game is not to be rushed and Zenyattas board is following the path that will lead to the greatest enrichment of shareholders, if they have the foresight and patience to hold in the face of the continuing adversity.
Good luck to all, keep your eyes on the prize
