Not to back BME (or not, I don't care either way), but 7 weeks on a product that takes MONTHS of protoype testing, long lead time orders on castings and machined components, etc. is not an extreme schedule change. I agree that publishing a date far in advance is a bad idea, but a 7 week slip in a process that may have taken 18 months is not that bad. I have been involved in work projects that are YEARS late because of various issues and changes. It is not trivial to produce manufactured goods to a tight time schedule.
