From all I have seen claimed it may be another 6 months before Robert has numbers of the type he has previously said are what he wants to wait to be able to release (i.e. 3rd party, for final design, etc.)
IMO if it takes another 6 months for the numbers to be released, the PPS will be trip zero's or the possibility of not being able to trade it at all.
Design 1st was redoing some things last week. Then Robert was going to do some testing. Not sure what those tests are since he is already happy with other test results. Not sure how long they will take either.
Ball is in their court. I would expect those who call should get updates weekly if not daily of what the progress is. Let's hope we don't continue to hear more delays, then maybe they are not as close as they have promised(pre-production). It's getting to the point of no return. Either you have it or you don't and the holding back of efficiency numbers is starting to look like they don't. Numbers are needed soon, very soon IMO.
