I had 100% so these must be new (some definitely can't done pre expac based on the description)

see attachment below>>

Yea, weird, I first thought that they had something to do with the new expansion in octber. But you can clearly do some of them (for example the gwent one).

But then there is one about the Order of the Flaming Rose and about destroying their campsites. I 100% the game and it didn't have any of the members of the order. According to the lore, they served Radovid after Witcher 2. But now their back?

Seems that we may be getting some more content :D

yeah, I've already tried doing the Gwent and the Potions one but nothing.
Apparently they're on steam as well but they show without names as placeholders.
At this point unless someone manages to do any of the 3 possible ones, I believe they aren't doable yet.
