Downfall? Cyberpunk has sold millions and has great reviews. You’re putting a bit too much stock into the faux outrage, and also greatly overestimating the effect the outrage will have on their future. There have been countless games launch with big issues and the studios turn out just fine. Look at Bethesda Game Studios. Look at BioWare. Look at numerous Ubisoft and EA studios.
They could announce Witcher 4 next month and people will be extremely excited.
Faux outrage? How many times has it happened before that Sony de-listed a major AAA title a week after release, refunds for everyone.
Just like after TW3, CDPR will lose a lot of talent. They'll have to recruit new people for TW4 and it might never get near TW3. I also doubt people will be very excited if announced next month. Evolution studios did not recover however since CDPR has GoG as steady income, they're not going anywhere. At worst they become like Valve.
The downfall has already happened, the question is, can they climb back up and top TW3.
