The market and economics decides prices. If enough people abandon ship and Sony determines it's because of game prices, they may adjust. I highly doubt the printing of physical disks impacts their bottom line enough to drop all game prices. Competition from Steam/XBOX, as well as demand dropping off naturally over time, is far more likely.
Video game industries are assholes except Sega for not caring about the consequences of video game stores losing business and Kingdom Hearts 4 sucks! Digital copies are the most expensive thing ever including phone, electric, and help me God credit card bills!
Sales drops over time is not the same as actual price drops. Unless psn has regular sales... which we know they won't, games will stay full price. The ps3/ps vita stores were testament to that, although indies on ps vita went on sale quit a bit, not first party titles.
this guy said "likely", so it's also just a speculation. Plus, Square Enix also go for GKC than proper Switch 2 game card. You'd thought they could cover the physical publishing cost as a major publisher but turns out they too cheapened out as possible as they can compared to other smaller publishers that made "backward compatible" Switch 2 game card (Switch 1 and Switch 2 upgrade pack in one game card rather than Switch 2 standalone executable)
Jacob Navok says that buyers will save money in an all-digital future. After the demise of physical games, the one-time Square Enix business lead predicts lower prices on the PS Store. He argues that having more publishers on the marketplace will encourage deeper discounts.
