Imminent BO would suggest DI is lying as his recent comments suggest he is busy speaking to large investors/ family funds etc. Why would they be doing this if a BO is being processed behind the scenes ? I personally believe a BO will eventually happen but perhaps a partnership first is more probable IMO.
The NT 10-Q reference to "subsequent events" and option accounting does not necessarily have to be a corporate milestone. It could be a simple as the early October price spike relative to the strike price for options.
