The Witcher 3 on Nintendo Switch is supposed to receive a major update in the future, but there could be the chance that this update is no longer in the works.

Saber Interactive, the team behind the excellent Nintendo Switch port of the popular RPG, has removed all references to the update on its VK social media page, where the update has been teased last month. The only reference to The Witcher 3 is found in a recent post which points to the CDPR official support page for all inquiries regarding the game. We have reached out to CD Projekt Red regarding the matter, and we will update the post once more information is available.
