About the sales number, problem is that from those 18 million copies, Cyberbug only sold 4 millions on 2021, while this hardly means CDPR will be bankrupt, it means a reduction on the interest on the game after the launch debacle and the ridiculously long patch cycle as some sources claim CDPR was expecting sales closer to the Witcher 3 levels, the massive bad reputation from the launch disaster sticked and the new gen version barely did a dent into fixing that what was their goal, it seems CDPR is abandoning the Cyberbug Titanic.
So, for the few true believers remaining that still believe CDPR will keep supporting this game in large scale are up to a rude awakening, CDPR scrapped their plans to add multiplayer functionality on Cyberbug engine and that means they are pushing hard their transition to Unreal right now and scaling back any remaining investment on RedEngine, if you look to their man power distribution chart, the part for Witcher 4 only grows larger. People are talking of "expansions" but lately the CDPR PR is mentioning "expansion", meaning, they arent commiting on a second expansion and it is questionable if the first expansion wont be just a glorified DLC.
Hilariously, CDPR setup an internal committee that will be elected by employees to advise the management if they have a massive fuck up like this on their hands again, supposedly a committee like this wont be made of sychopants that say what the management want to hear as they are on a group, and in theory, as there is less of a threat of they losing their jobs, they will speak their minds. Of course, one could ask the question of how about the management stop having their heads on their asses?
