The problem is that Kena, Stray, Sifu and PSVR2 stuff is so niche that no one cares about them. At least not on message boards. I do agree that Returnal, GoT, Wolverine, and Death Stranding are proof that Sony isnt all in on sequels.
Another problem is that unlike past gens, when we only got sick of games after the third entry in the franchise, these games are so long that by the time we finish the second game, we are done with them. Horizon FW, GOW Ragnorak, TLOU2 started feeling samey just a few hours in. I enjoyed them but they didnt do much different to keep me interested despite their 5-7 year dev cycles. Final Fantasy games on the other hand feature new characters, new worlds, new combat systems, and thus can get away with having over a dozen sequels like Zelda.
Hell, I think Nintendo doing a straight sequel for Zelda is going to blow up in their face despite how beloved BOTW was. It will still review well like GOW, Horizon and TLOU2, but you will see a bigger backlash from gamers who are going to complain about it being too samey. Gone are the days of Wind Waker, Twilight Princess, Skyward Sword and BOTW feeling completely unique and different from their predecessors.
Uncharted 1-3 took just 4 years. GOW1-3 released in a span of 5 years. By the time Horizon 3 and TLOU3 come out, these series would be 12-15 years old. Its hard for anyone to care about a story that takes that long to end.
