Neon White has been rated by the ESRB on those platforms and possibly Game Pass.
Neon White appears to be coming to Xbox Series X|S and Xbox One in the near future, considering that the game has been rated for those platforms on the ESRB , which is the video game age rating body in North America.
Usually, it is a rather explicit indication of the subsequent release of the games, even if there is always a margin of doubt or error on the catalogs of these organizations, so we look forward to any official communications or announcements in this regard.

It’s not the first time that possible clues about Neon White for Xbox have emerged but, in this case, the question seems a little more tangible, given the specific cataloguing. The game remains a strong candidate for Xbox Game Pass , which remains a well-founded suspicion.
It is a very particular indie title, which would find a perfect place in the Microsoft subscription catalog. Furthermore, having previously been released on other platforms, its launch directly in the Game Pass catalog would increase the attractiveness of the title on Xbox.
Neon White is currently available on a range of platforms, including PC, PS4, PS5, and Nintendo Switch.
