If Apple did in fact choose to set its production levels for the long-term, that would largely account for the shipping delays, as there tends to be a rush of buyers when a product firsts hits the market, with demand flattening out over time.
So, even though early demand may be higher than Apple expected and it can take a while to get a new plant running up to full capacity, the effects this will have on Apple's image and bottom line is minimal. The Mac Pro delays may be the worst in recent memory for Apple, but they only impact a handful of the company's customers — most of whom are probably willing to wait for the new machine anyway.
Regardless of the underlying reasons, analysts are likely to quiz Apple CEO Tim Cook about the delays during next week's quarterly earnings call, even if it doesn't have a hugely material impact on the company's figures.
