Apparently, Apple is pretty damn confident that you're going to want a new iPhone that simply sports a handful of hardware changes (and no difference in overall design).
Apple is reportedly telling manufacturers that it needs up to 90 million of the iPhone 6s, which it is expected to debut this fall.
From the Wall Street Journal:
Apple is asking suppliers to manufacture between 85 million and 90 million units combined of two new iPhone models with 4.7-inch and 5.5-inch displays by Dec. 31, according to people familiar with the matter. The screen sizes are the same as in the iPhone 6 and iPhone 6 Plus.
By comparison, Apple last year ordered a then-record initial production run of 70 million to 80 million for its first larger-screen iPhones.
The iPhone 6 and the iPhone 6 Plus are the best-selling devices that Apple has ever made, so this is a pretty big vote of confidence from Apple on the demand for the 6s.
As is the case with all of Apple's mid-number change upgrades, the iPhone 6s is not expected to go through any significant design changes. Reports have suggested that it might be a bit thicker, but as far as screen size of overall frame dimensions things will likely stay the same.
The new phone is expected to come equipped with Force Touch technology, which basically consists of tiny sensors in the retina display that make the device able to distinguish between a light tap and a firm press. It's already in use in the Apple Watch and gives users a wider range of controls and options based on the pressure they put into any action.
