Well before the iPhone X was officially unveiled, we'd heard plenty of rumors that Apple was struggling to make as many as it needed - something that's backed up by the delayed pre-order dates of October 27 and November 3 respectively for the most expensive of the company's new iPhones.

Now well-known KGI Securities analyst Ming-Chi Kuo says it won't be until well into next year that Apple manages to churn out enough iPhone X handsets to keep up with demand, based on an investor note seen by MacRumors.
