If anything, next gen Xbox leaks and Sony's new statements imply a shorter generation. This generation started with great official prices but will end up with bad prices. Production costs just aren't going down. PC is pretty much killing Xbox and is likely hurting Playstation hardware sales as well. Everyone was hyperfocused on Xbox vs Playstation, ignoring the elephant in the room (PC). At the prices they're going for, there is a decent chance that PS5 would fail to outsell the PS4 even if Series XS production ends.
Still... I'm looking forward to that GTA6 effect. Coupled with a hypothetical permanent price drop, 2025 could be just as big if not bigger than 2023 for Sony.
