It seems to me that he's been very open about the process form the beginning. Openness is always a good trait when you're handling someone else's money.
Yes, it's a little like watching sausage being made, but I don't think anyone could reasonably accuse him of trying to cheat people. As frustrating as putting up with these delays must be for those who ordered, how much worse would it be if the whole process was a secret?
In the end I hope to see him release a terrific machine, having earned the trust of the collector community in the process.
