This is circling the problem.
There's no way to combine keyboard and living room setups if competitive FPS games require a monitor and a desk, they are two distinct and irreconcilable experiences. For a long time, consoles and living rooms were, and still are, better suited for third-person games. Therefore, the viable solution is for a console to offer a separate keyboard and controller, two items in the box.
Someone suggested that a portion of the public simply wouldn't use the keyboard at all compared to the Xbox One's Kinect, but I believe they would use it eventually, after all, the keyboard is still the best way to play FPS games. it's the games that justify the peripherals. I would even agree with the premise if, for example, whoever made the product I theorized didn't also make games targeting both peripherals, that is, competitive games, real-time strategy games, without forgetting to make third-person games.
