This was confirmed by Blizzard on their blog.
Snow storm released new information about the upcoming season of Diablo III. In an entry on its blog, the study revealed some of the expected news for the April 15. Interestingly, they are expected technical improvements in the titlelike a increased resolution on Xbox Series X|S.
The title released in 2015 still had no improvements for the latest console generations. Until the version of the series X is the one that comes from One S and not One X as originally planned. This gave a blurry effect and the teams had warned of the arrival of a patch to correct it. This will be done with patch 2.7.3 and it will look like this:
- Update 2.7.3: Updated resolution on Xbox Series X|S. On Xbox Series X the game will run at native 4K resolution and on Xbox Series S at 1080p.
