Arstechnica- In unveiling the new PlayStation 4 and its DualShock 4 controller tonight, Sony notably neglected to include any information about the precise size of that new touchpad sitting front and center on the face of the redesigned controller. But we didn't let that stop us. Using publicly available information and press photos of the controller, Ars has been able to generate an estimate of that touchpad's size: 52-54mm (2.04"-2.12") across and 23-29mm (0.9"-1.14") high.
