I agree with you, because it is frustrating to be kept in the dark, especially when delays aren't revealed for such a long time and then are simply referred to in a passing way.
However,  I am becoming used to their style which is unlikely to change, and they do try to put a positive look out there, which I myself have thought would cause a real rise in the share price.  I now will be looking more closely at what they actually do versus what they say, because who will perceive more accurately when this stock will finally be rewarded for it's business and tech- the impatient investors or management?  
I think we've a longish way to go before that, perhaps even a year or more, and my biggest worry now is the geopolitical risk. Having said that, I am selling nothing, but hanging on grimly.  I have no animus towards traders, but it's not my style.
