Either the PlayStation 4 controller is really big, or the Xbox One controller is really small—but the picture you see before you shows exactly how vast the size difference is between the two. It's actually the former—the PlayStation 4 controller, better known as the DualShock 4, dwarfs its predecessors and its counterparts.
Previously, the Sony controllers were heavily criticized for being too small, so it looks like the engineers at the company have taken it into their hands (ha-ha!) to redesign the controller from the ground up and fit hands that don't belong to Japanese schoolboys. Needless to say, the new controller looks a whole lot more comfortable than its predecessors, and it'll be interesting to see how it holds up against the Xbox One's controller.
