What AAA games sell on Japan? Final Fantasy?
What game of PS5 have 300k physical now?
Your assumption doesn´t have an anchor on the reality of the market.
PS5 can´t maintain 3 games on top 30.
This is reality of market, rest is wishful thinking based in hopes and dream, I ´m sorry.
PS5 will get the next Monster Hunter game and probably Dragon Quest 12 too given its using Unreal Engine 5, both massive system sellers.
PS5's situation now is not indicative of its long term prospects because it's situation now is the result of a severe chip shortage that will not last forever.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
