Well if Microsoft isn't releasing a Pro varient this year maybe Sony says let's pause. We already have the upper hand and consumer confidence. Why push out something we dont have to yet. Maybe they refine it a little more with another year wait and launch when the newer xbox is to release. Would be a smart move on Sony's side unless they already have mass produced units.
Sony competes vs pc market too, especially in europe that is sony stronghold, they want to give their consumer base a highend option, by holiday 2024 base ps5 is at best midrange pc equivalent in terms of cpu/gpu, and remember 4 more years left till ps6, in 2025 base ps5 will be only low end pc equivalent, performance wise.
So imagine perfectly plausible scenario- gamers wanna play sony exclusives, but in 2025 they notice how fricken weak base ps5 is, so they say- fk it, i will get into pc for 2-3x more performance(u could get 2x with 3090/3080ti already, which now is 600$ 4070super, hell 500$ 7800xt has 60-70% more performance too and better rt vs base ps5, those arent topend gpus but midrange and very affordable ones).
