This is what I expect, really. Switch has done plenty of unique gameplay experiences like LABO, Ring Fit, and Mario Kart Tour with peripherals that leverage the existing form factor and sensors of the device. The ability to change how we play games is built into the DNA of the Switch. Features like HD rumble and gyro aiming can seamlessly integrate into a 'traditional' gaming experience and enhance it, while developers can choose to push the envelope (or just mess around) by using the rest of the Switch's features (like how Skyrim has Twilight Princess style sword controls lol). This is unlike the Wii U's second screen which... well, I never found it a particularly desirable feature in games, and felt like a distraction and afterthought.
When I want a 'better Switch' I don't literally mean I want the existing model with the T239 crammed in. I do want additional IR sensors, enhanced haptic feedback and motion controls, an OS with features like quick resume and streaming, and some asymmetrical multiplayer. I even want a touchpad on the controller. None of these change the core of the Switch which is a hybrid console. But all of these can make a console 'better' and could be worth the added cost. Even the Vita crammed a bunch of features like a touchscreen, back touch pad, gyroscope, camera, mic, etc. but it was still a PSP2 at the end of the day, and these features were optional.
I am skeptical of this supposed mandate for a new major 'gimmick' that will supposedly transform how we play games, that people seem to expect of Nintendo. It's not like the Wii U's dual screen and 3DS's 3D were major paradigm shifts. And unlike motion controls and touch screens, they didn't make the cut.
