There are many, many downsides to Sony ending physical disc production in 2028. However, one small silver lining, according to a former higher-up at Square Enix, is that games will get cheaper.
On Twitter, Jacob Navok, director of business development at Square Enix from 2010 to 2015, commented on the nature of video game pricing. "Competition between publishers is what drives pricing pressure, not competition between digital stores," he says. "This is because publishers set pricing on digital stores."
