Quoted from above.

"Now, CD Projekt Red is celebrating The Witcher 3's ten year anniversary in style, as it announces that mod support is coming to console. In an update later this year, cross-platform mod support will roll out on Xbox Series X/S and PlayStation 5, giving console players access to mods for the first time."

It is unknown how many of the many thousands of mods will get support or how this will be handled as far as I can find so ffar.but it's fair to say we won't be seeing this...

Very glad I didn't start my next gen patch playthrough just yet. I am very excited for a higher difficulty over death march and possibly modifiers akin to a survival mode, I'm sure there are mods for adding in a theif system and things like that but mainly I'll be choosing style mods and modifiers if available.

Okay. From what I have learned it'll be curated mods through some third party site that will take care of them and approve them to be used in the game. Very much like Skyrim, I can't see much of interest being added here, certainly no extra quests or transformative content.
