This is the 2nd time they raised the price of Xbox consoles this year. You can guess why.
Xbox Series S 512 increased to $399.99 from $379.99
Xbox Series S 1TB increased to $449.99 from $429.99
Xbox Series X Digital increased to $599.99 from $549.99
Xbox Series X increased to $649.99 from $599.99
Xbox Series X 2TB Galaxy Black Special Edition increased to $799.99 from $729.99
You used to be able to pay Microsoft ~20€ to enable developer mode, so you were able to sideload emulators and other homebrew apps to the Series S/X. I’m not if it’s still possible.
