I have a bit of a theory about the PS5 Pro beyond Sony trying to milk more money out of their aging platform. Between the announcement of no disk drive, the high price point, and Gamestop recently announcing they are going to put an emphasis on selling retro games, I think this is a dry run for next generation, at least from Sony's point of view. I think they want to see how well received a digital only, super expensive console will go over with consumers as a way of judging whether or not to continue using discs or not. Gamestop likely knew about this well before we did and have been preparing to pivot their focus on retro games as a way of preparing for the upcoming storm. I believe Nintendo confirmed their next gen console will still use physical media, but that console alone isn't going to keep Gamestop in business. As for Microsoft, I don't think there is any doubt their next gen XBOX will be digital only seeing how they've been actively phasing out physical games already this gen anyways. But back on point. The PS5 Pro is a test to see where the PS6 will go, and if people's general reactions so far are anything to go by, I think Sony will at least reconsider going digital only next gen, but we'll see.
On a personal note, the PS5 is already my least favorite Sony console, mostly due to the lack of worthwhile exclusives. Like previous Sony consoles, i just assumed the games were coming, however between most "exclusives" getting mutligen releases between the PS4 and PS5, as the PS5 exclusive games being somewhat sparse, I mostly regret owning a PS5. With that said, there's no way in hell I'd purchase a PS5 Pro, even if it had a disc drove or was prices around $500 or less. Not only that, but I noticed a marginal difference in performance during the tech demo video when comparing a standard PS5 to a Pro. Honesty, I can't justify a PS5 Pro purchase for anyone. I'm sure some Sony diehards will buy it anyways, but as for me I'll likely forget it even exists in a few months. Sony has really been shitting the bed this gen and as someone who has loved all the previous Sony consoles, it's sad to see.
