Jonathan Blow revealed to IGN that The Witness would be released on Xbox One next month.
They are aiming for a September 13 release date and also reconfirmed the iOS version. The Xbox One version will be more or less the same as the PS4 and PC versions with a few technical differences. The iOS version on the other hand will be different with new control schemes that are being worked on right now. There’s no release date for the iOS version yet. Nicola really loved The Witness on PS4.
The Witness is available on PlayStation 4 and PC with an Xbox One version coming next month.
