I find it very hard to believe that this is a mutual decision of CDPR and Sony. If it was one, it should have been presented as such to avoid further PR and stock disaster for CDPR. What happened is too extraordinary for the industry, i dont really know, but i more on part with the version where Sony decision was caused, apart other unknown reasons, by the fact that the CDPR announced refunds without making any specific agreements with Sony.
The decision was mutual, although, from the facts, what was seen is that Sony was resistant to refunds (the CD had already released this before).
what happened is nothing 'extraordinary', what has been 'extraordinary' is the shouting of the unprofessional press around gossip, alias, gossip that they themselves fed for years (before the launch) to gain the attention of their audiences.
A storm in a small glass of water
The CD follows the sales leader for PC on Steam, if that weren't enough, sales of the game The Witcher 3 are still extremely high. Not by chance, they are also offering, as I understand it, refunds for physical copies of the game. Perhaps this, in a positive way, is 'extraordinary'. I, Iskras, do not know of another company that has been as concerned with refunds as CD.
Future
I hope the best for CD, its workers and the game. But I would also like the company executives to be more realistic about business, but that is just my wish, I cannot intervene. If it depended solely on my will, I would continue to be a game producer and not an 'agent in the business world' - even if it risked being 'eaten' by some larger monopoly.
