Xbox is dying and Nintendo mostly moved to portables, so in some years there should be only one home console brand as he says: PlayStation.
Combining the sales of all home consoles and removing the user overlap between them there was almost 200M users in the PS2 generation, and around 250M in the PS3 and PS4 (if counting Switch as home console of that generation) generations.
By "one console future" they mean the pc, they just aren't saying it openly because they know people will give them shit for it.
Eventually there may be only a home console left, PS. And console, PC and mobile are in a trend of slowly being merged in a single global market too.
In fact, PS4, PS5, XBO, X|S or Steamdeck are essentially PCs in terms of hardware, and Switch/PS Player essentially have a smartphone/table hardware. Mobile and PC hardware are slowly merging too.
For them, in terms of business, with AAA budgets highly growing every generation these 200-250M users of the console market at some point won't be enough, this is why all big publishers are expanding to console + PC + mobile.
Yoshida loves consoles too.
Yes, and he and Shawn started the current PC + GaaS push in the Sony 1st party games. But to be fair, anyone seeing the market numbers, how the budgets grow every generation and evolution of the market would have done the same.
Because the alternative would be to gradually stop making AAA games starting by cutting the lower seller games.
Yoshida is passionate about indies, so he moved to create and lead PlayStation Indies, where he is very happy.
