Please tell me where you have found GTAV, COD etc LTD sales numbers in South Korea, Taiwan and China? Software sales reported by system have been good on PS4 despite being an old system and in a region where console gaming is growing massively.
Not everyone wants to play on PC, and this is shown as console gaming is becoming ever more popular in those regions.
PS3 went down to $199, while PS4 stayed at $299. PS4 did not get a price cut because Sony decided so. Its been able to sell 120M. Could it have sold more at $199? Obviously but Sony prefers higher profits than PS4 selling to 130M.
You seem to be struggling with the concept that Playstation is still growing. PS5 will have higher peaks and more software/hardware sales than PS4's peak. Nintendo may be the market leader like in Japan, but Playstation still has a significant marketshare that is unrivalled as Xbox is non existent in Asia.
Ask that to the 120M PS4 players. People play on consoles for numerous reasons: its simple, convenient, easy to set up and maintain, exclusives, its cheaper etc etc
Playstation continues to show big growth in these countries so clearly not.
The discussion was about those in Korea, Taiwan or China, not Worldwide. And there, PC gaming is much more prevalent than console gaming, and as a result, they don't need to buy an extra console for those games.
Also, cheaper is not fully true either. A console is cheaper than a PC with similar specs (especially now when GPUs are almost unobtainable except from scalpers), but the games are generally cheaper on PC.
As for the big growth, we'll have to see. PS5 is outpacing the PS4 so far, but the console is only out for half a year and thus we don't have any long-term trends yet. But I agree the situation is favorable for the PS5 to grow potentially in Korea, China and Taiwan, and in RoW in general right now.
