You seem to be having trouble understanding the difference between the most optimistic, earliest physically possible ship date and the guaranteed delivery date.
Hint: the earliest possible ship date isn't a deadline of any kind. Hope that helps.

The chip design is almost complete. We're starting sales now because we're at the point where we the calendar of remaining items is fairly fixed, and we're confident we can deliver.
Note the date on that quote. That sure doesn't sound like an earliest possible ship date. That quote says just the opposite. "Nearly complete", "remaining items fairly fixed", "we're confident". Wrong, wrong, wrong.
Fact is, they are late. Months late.
