Somewhere out there there's a super-sized working PS4 controller that Sony created during the development of Knack according to Mark Cerny. Wild guess: the super-sized controller influenced the PS4's new trigger design, based on what Cerny says in the video below.

DISCUSSION

People who disliked the ps controller are gonna be upset that they essentially created the PS4 controller with 8 year olds in mind ( I think the dualshock controller is fine).
