If PlayStation slows down the entire Sony company is in trouble. How do you think the market will react when they realize each following PlayStation console will sell less than the last and that most of their games flop on PC and generate very little additional money on top of delaying the rate that their games release and sales of those same games on PlayStation consoles?I think they will be fine and will make money, but won't make as much money as they could have if they bet on being THE entertainment centre for your living room. They won't be, and the PS5 will sell less than the PS4. I'd be surprised if it reaches 110M sales, nevermind 117 or 120M.
They are betting their entire future on more GaaS hits like Helldivers 2 and becoming a third party publisher like Xbox. It might even work out for them but it sure won't work out for fans of their single player games.
Some weird stuff is already happening with half the people refusing to upgrade from PS4 and games like HFW underperforming.
