Have to analyze why exactly the PS5 was a let down for so many people.
First party output seems to be the main issue. This was kneecapped after their live service gambit failed. They straight up lost a studio due to Concord, and while they didn't lose Bend or Bluepoint (thank god), the cancellation of those studios' live service games meant their output this gen amounted to a write-off. If Sony put all these studios back to work on the games people actually want, they could easily have something good cooked up for PS6.
Next is the issue of development times, which also affects third parties. They've been getting longer and longer every gen. It's not just a huge business expense, it's also bad for players. Nobody wants to wait 6/7 years for a game. Conceivably, a dev could release a game at the very end of the PS5 gen and then not have their next game ready until PS7 launch.
There's been a lot of moaning about the likes of Ghost of Yotei, but it's an example of Sony finally getting things under control. Sucker Punch made it in less time than Tsushima for a similar budget and it still looks pretty good to most people. Astro Bot took just 3 years to make and ended up winning GOTY. The writing is on the wall that the market doesn't actually need everything to be cutting edge - leave that to Rockstar to burn billions of dollars and over a decade chasing.
There were also real world events which factored into PS5's disappointment. We had a pandemic delaying games left, right and center. There's projects being worked on that even today are feeling the effects. You can't just delay a year and expect to ever make that time up. Then there was the semiconductor crisis which caused massive console shortages. This no doubt drove last minute decisions to port a lot of their PS5 releases to PS4.
That, plus a lot of games going to PC, is going to gimp the perceived value of the PlayStation 5. Yeah, it's nice to have games on PC as a sort of fuzzy "we are all gamers" Phil Spencer kumbaya moment, but it's also going to fuck the attractiveness of the brand. When people say "no games", they mean no exclusives games. Perhaps Sony need to get more protectionist with their releases if they want the console to actually be worth owning.
