i am in the same kinda boat as you, I am beyond delighted with the console, what a great bit of kit and the price is unbelievable.
I will say i am a bit disappointed in the games price increases but tbh it was not surprising. i think i am slightly lucky that i have a massive back log of games, i don't have to buy any new generation games if i have to and still play something fresh every month for the next year, even two years lol, spiderman, days gone, ass creed origins/odsy etc etc
As for the ps4 games specifically horizon zero dawn 2, i am not sure i like it but i guess the engine is super scalable.
the truth is the main reason i want a ps5 was for the load times and extra performance for my favorite games, just being able to get the console is a win win in my book.
As for games going to pc, it never has bothered me, i can understand why people don't like it, but in all honesty, it has never really bothered me.
