Patents registered by SCEA last month included one for a trackpad device. That sounds a bit familar, doesn’t it?
“Comprising: a case having first and second major surfaces; a visual display disposed on the first major surface; a touch interface disposed on at least one of the major surfaces.”
Two weeks ago, VG247 posted shots of a PSP2 dev kit, which showed said trackpad on a PSP go-like device.
PSP2 developers, however, have since reverted back to a kit similar in form to the original PSP-1000.
