The Xbox Series X and PlayStation 5 next-generation consoles are promising resolutions up to 8K, but Phil Spencer has a clear preference between pixel count and high frame rate.

Speaking with Stevivor, Phil Spencer stated that, while they have given developers the tools and the freedom to do what they want while developing Xbox games, he wants the games to feel as good as they can look nowadays on Xbox One X. This was not possible in the current console generation, as the CPU is underpowered relative to the GPU. In the future, however, he would like to focus more on the feel of the games, and not just resolution.
