Similar to the jump from PS3 to PS4 / Xbox 360 to Xbox One, there will probably be a premium for next gen titles. We're talking about 5 euro, which will start new games at 75 euro. It starts with NBA2K21. They already mentioned the price: https://www.pcgameshardware.de/Playstation-5-Konsolen-265878/News/Boykott-Aufruf-von-NBA-2K21-nach-Bekanntgabe-von-Preiserhoehung-1353563/
Do you think that's too much, or is it still okay?
A game costs 70 euro (which is a lot of money, but it also depends on the game), I don't think 5 euro really matter.
