Yeah, not to mention the fact that used games/hardware are where the make the majority of their revenue from.
Digital isn't strong enough yet for consoles and not nearly widely enough accepted to be a significant threat to the used game market. Hell, we saw Microsoft having to pivot backwards away from a more digital console that potentially restricted used games because of the massive backlash.
It will eventually happen, but it will not be for many years. It will take a while for the console market to get acclimated to digital as the primary purchase method for games, and most countries still have a ton of work that needs to be done with their internet infastructures to support a mostly digital only future.
