Jefferies & Co analyst Peter Misek is claiming that Apple will begin production of the iPhone 5S at the end of this month, with the handset released in late September or early October, reports Business Insider.

The weight you give to this confident prediction may depend on the length of your memory: Misek is the same analyst who predicted back in January that production would begin in March with a launch in June or July. When March rolled around with no sign of production having started, he claimed it had been delayed by supplier issues with ‘new casing colors.’ For the 5S, you’ll note, not the plastic iPhone.

His checks indicate that Apple has been shifting its orders to cut back on iPhone 5S production while increasing low-cost iPhone product for the end of the year.

Then there are his stock price predictions:

The great thing about the prediction game is if enough analysts predict enough dates, some of them taking two bites of the cherry, at least some of them are guaranteed to be right – even, conceivably, Misek.
