If I didnt have a PS5 already (bought mine May 2023) - I would have bought this easily.
But the fact that it doesnt have a disc drive (despite being fully digital, I still have some PS4 games that are physical) made the decision making easier.
I'll stick with my PS5 and likely will get the PS6 on launch (or whenever I'm able to get it per stock and availability).
I could jump into getting a PS5 Pro maybe in the future but...highly unlikely, the AI up-scaling portion gives me doubt.
If anything I'll stick with playing games at performance mode on PS5 and play them again years later on a higher spec PC for higher resolution and framerate.
