One of the analysts at a brokerage company told the Strefa Inwestorów portal that the add-on has not yet been announced because it is in the development stage. At the same time, CD Projekt allegedly wants to release it before the release of GTA VI.
I have not included the DLC for The Witcher 3 in my model, but, like everyone else, I assume that CD Projekt will try to release the DLC before the new GTA release date in order to avoid a difficult period for other games. So definitely before November, probably around the third quarter. I think September is the best option. Gamers are on vacation in the summer, and September seems like a good "back to school" period. However, the situation may change. Maybe they will come up with the idea to release it in two or three months.
According to the analyst, the release is possible in September, but an earlier launch is also possible.
