Apple describes Force Touch as the most significant new sensing capability since Multi‑Touch.
Force Touch uses tiny electrodes around the flexible Retina display to distinguish between a light tap and a deep press, and trigger instant access to a range of contextually specific controls.
The WSJ's sources say, "the touch technology is one of the changes that Apple plans for the next versions of its iPhones due for release later this year".
Notably, this report corroborates another from last month which also said that Apple would be adding Force Touch to the iPhone 6s.
