The Witcher's official Twitter post said today that they decided to let their internal team do the rest of the work for the next-generation version of The Witcher 3. The scope of work that needs to be done is currently being assessed, so the release of the second quarter will have to be postponed until further notice, and they will complete the update as soon as possible.
Originally outsourced to Sabre Interactive (who was in charge of NS development) and scheduled for release in 2021, cdpr announced a postponement of the game until the second quarter of this year in October last year, but said plans could change. Now that the ticket has been jumped again, the new release date has not yet been announced, and we will continue to pay attention to it.
The next-generation version of The Witcher 3 will "receive a double effect enhancement from both visual presentation and technical aspects", and players with this generation of The Witcher 3 can get the next-generation version through a free upgrade.
