A Sony patent that was filed back in 2015 but only recently published, shows a set-up that isn’t too dissimilar to that of the final build of the Nintendo Switch. You can see in the image below the removable controllers which are reminiscent of the PlayStation Dualshock controllers attached to each side of the device. However, there’s no mention in the patent suggesting a dock that would allow the user to connect the device to the TV.
Will this ever see the light of day? With the recent announcement that Sony are stopping Playstation Now support for the Vita, it wouldn’t be surprising if they were researching different ways to break into the handheld market once again.
You can read details of the patent in full here (although it’s in Japanese).
