you say that the alpha prototype isnt completed yet.....are you sure? They arent known for their communication skills, and like lumenge suggested, they may not wish to announce that until rigorous testing/optimization has taken place.

Just playing the devils advocate here, but its been a very long time since Ajit suggested things would be buttoned up in "weeks" not quarters!...so what have they been doing in the meantime, if they dont have a working prototype in hand? 

time for some answers and all this cosy nda BS can piss off!
