It'll have a touchscreen, though I don't think core games will be built around it. Still, when you're holding a device with a screen in your hand, the first thing most people will do in 2017 is touch the screen to interact with it. I think it's pretty much essential from a user experience perspective.
Other than that, it'll probably work with mobile ports, too. But for the core gaming experience I don't expect a touchscreen at all.
