"Can it be any wonder that a level of secrecy is maintained under NDA." 

For me, yes, it is definitely a wonder that if things are as many longs here believe, that the secrecy has been so well maintained, purely as reflected by the share price action.  I sure as heck hope no one is stealing our tech secrets.

"In terms of industry timelines to develop and build new products there is absolutely nothing unusual about this."

Wholeheartedly agree with the above, which is why I tend to believe that 6 months from now, we will be saying the next six months will tell the story.  I find it difficult to believe that the tech will work as now constituted - I believe adjustments/refinements will be needed, and we all know those things take some time - about 3 or 4 times the amount of time most believe :).
