This is a joke post, right? A touchscreen isn't new, and it's demonstrably worse than buttons. No, no, no.
Some people don't seem to realise we've been able to game on smart phones and iPod touches and tablets for years now and the most satisfying games are the ones that use the touch screen in ways, like swipe and tap etc and not fake buttons or fake dpads. Fake buttons are bad, it's why some companies make bluetooth pads and screenholding pad handheld things with buttons and stick sand dpads, because it's shit without them. It's why there are some companies that make little button and stick things you attach to the screen over the fake buttons so you have "proper" buttons to use in those games.
Everyone going "wow, innovative, 10/10 move, keep it up Nintendo!" go whip out you iOS or Android smartdevice and maybe try booting up a platofrmer that uses traditional inputs (buttons and dpad). Maybe load up an emulator if you can and try playing Super Mario Bros or World and see how much worse it is than on an actual pad. Maybe try and play an action game in the style of DMC or Bayonetta (if any even exist on those devices).
Now, if they do use the "buttons pop up" thing that would be cool in a "wow, technology is crazy" way and be a million times better than touch screen fake buttons, there is how they feel, are they like, squishy? are they like popping bubble wrap in that they are very clicky? Can you mash on them?
And even then, you get the issue of button placement. If every game has it's own popup buttons that can be different shapes or in different places then it creates an issue with muscle memory and knowing what button to press/where to press without looking at the controls on the side of the pad.
Like, you could have a Mario game that just has run and jump, simple. But what are those buttons called? Are they A and B? Run and Jump? 1 and 0? Then you boot up Dark Souls 4 and now you need to press X and O and Y. Now you play something else but A and B are flipped, not the Nintendo way but the Xbox way. It can just cause confusion on the same console. People already struggle going between Xbox and Wii U and PS they could have this problem now between games on a single system.
