Update: Ubisoft has now confirmed the existence of this special 20th Anniversary Edition, revealing that it was accidentally made downloadable earlier today and won't actually be releasing until some point in early 2024.
Here's the full statement from the company:
"Well, looks like the cat’s out of the bag, dagnammit. Happy 20th anniversary to Beyond Good & Evil! While we cannot wait to show you more about this special edition, more news to come in early 2024! An early development version of Beyond Good & Evil 20th Anniversary Edition was recently released to some Ubisoft+ subscribers by mistake. We apologize for any confusion and want to assure our community that this version is not indicative of the final game."
"As we celebrate the 20th anniversary of Beyond Good & Evil, our commitment to delivering a game that meets the high expectations of our fans is unwavering. We're excited to announce that the official launch is set for early 2024, and we're dedicated to making it an experience that truly honors the legacy of the original. Thank you for your understanding and continued support."
Original story: After being rated earlier this year by the ESRB, Ubisoft's Beyond Good & Evil 20th Anniversary Edition has now appeared on the Microsoft Store for Xbox (update: it's since been taken down again!).
It will be optimised for Xbox Series X|S and will also be available on Xbox One. In addition to a full description, a number of screenshots are also included in the gallery section. There's no release date or price just yet.
Here's the full description which mentions up to 4K resolution, 60fps and Smart Delivery:
