That has been the case for a long time, Sony has no confidence on PlayStation long term so instead of reinvesting to strengthen PlayStation position they use that money to help other divisions. All their plans reflect that, they are ok with PS5 selling less than PS4, they are porting their games to PC, they are afraid to try again on the portable market, they are making and announcing less games than ever, etc.
I remember people dismissing my observation that if you see a Sony presentation PlayStation always comes of as an after thought, as if Sony Pictures, Sony Movies, cameras, electric cars, etc were all way more important than mere video games. It's a self fulfilling prophecy, they believe consoles are going away and probably think the same about AAA single player games.
What is funny is that any of these movie studios would kill to have a business as strong, profitable and with such a good perspective for the future as PlayStation, yet Sony takes it for granted and doesn't seem to value it at all. How much would MS be willing to pay for PlayStation or to take their position in the gaming market? A lot.
