I can say with certainty that the next iPhone will have a 5" screen. Or maybe a 4.5" screen. Well, a 4" screen is possible. Conceivably a 3.5" screen. Maybe something in between those figures. Or larger than 5" or smaller than 3.5".
That pretty well sums up the current range of 'confirmed rumors' about screen size. See how ridiculous it is to play that game?
They really need some kind of accuracy checklist for analysts. Every time they make a prediction that's wrong, they lose points. When they make a prediction that's right, the earn points. It becomes illegal for any media outlet to quote any analyst with a negative score. That might fix the problem - and slow down the ridiculous unending stream of nonsense being thrown around.
