Where was the 2027 date announced? As far as I know, CDPR only confirmed that Witcher IV won't launch in 2026. After the cyberpunk debacle, I'd rather have them spend more time on the game. It only started full production in November 2024. I still have faith in CDPR though, especially after they fixed Cyberpunk with the 2.0 patch + dlc.
Also, considering that next gen consoles will probably launch in 2028, a 2028 release would allow CDPR to push the extra mile in terms of fidelity and environment simulation.
