this is not an official design and its not made by anyone related to Microsoft
A very rudimentary concept design for a Next Gen Xbox controller. the basics aren't that much different from the design I did for the Xbox One controller back in the day,
but this time I think I made a more realistic one.
This isn't a drastic redesign but an attempt to optimize it for modern games.
More and more games, especially PC ports, start to run out of buttons... they did for years honestly... so bringing back the Black and White buttons of the original Xbox is a must IMO.
those buttons are perfect for stuff like Inventory macros in RPGs, Switching Weapons/Tools in a game like Fortnite or Minecraft and other stuff without occupying the main Face- or Shoulder-Buttons
The placement of Menu and View (Start/Back) are also chosen so they can actually be used for something important. in many games View is used for inventory screens, so you might want that button to be easy to get to.
being just left of your thumb makes sure that quickly changing something in your Inventory is easy and fast.
BUT with this placement it could also be used for more important stuff.
and last but not least, the Touchpad. The PS4 has one, and history shows us that companies usually look very closely at what the competition is doing (I mean look at the Switch Pro controller)
it can serve as an easy way to browse the web, and quick gestures for games.
cheap LED indicators for Player Number and Battery are also there.
