Here's one summary of what the NX is going to be, based on all of these patents:
- The Nintendo NX controller has a screen - but instead of being a discrete screen, the screen is embedded into the body of the controller itself (see Figure 9b to get a better idea) (this ties into the Sharp freeform screen patent Nintendo filed a while back).
- The screen is a capacitive touchscreen, like on a smartphone, tablet, or the PS Vita.
- The controller has two analog sticks and four shoulder buttons, a speaker, as well as a cartridge slot.
- The controller has a discrete computing unit, and it can offload processing to the main console (this ties into the cloud processing patent that Nintendo filed a while back).
- The second screen is strictly used as a supplemental screen- the examples in the patent include for instance a weapon wheel showing up right next to the analog stick in a shooter. - This means that the controller can effectively be programmed for whatever button layout the developer wants, instead of a game having to be made for the controller.
- The controller seems to be a discrete handheld unit.
- The screen is 16:9.
- The screen may be autosterescopic 3D, like on the New 3DS.
Basically, it sounds like the NX has a discrete handheld that also acts as the console's controller. The handheld is a powerful system that has its own cartridge slot, and can offload processing onto the main console unit when necessary. The handheld does not have a discrete screen - it's very body is a screen. When acting as a controller, the handheld's screen provides for infinitely reprogammable buttons, meaning games are no longer designed around, or held back by, controllers - the controller gets infinite versatility, while also sticking to the kind of shape and layout that consumers are most familiar with.
