Why would they do this, when Apple would be, in one fell swoop, handing Sony (and M$) one of their most cherished objectives on a silver platter? By which I refer to the elimination of the used video game market. Far more than half of all physical console media sales are used, so even if prices dropped by 50% (which they wouldn't), Sony and M$ and the rest would see revenue go up sharply. Especially considering how the demand curve works. I forget where I read it, and the recent articles on the topic are spamming over my Google-fu, but apparently an X360 game bought new will be resold something like 6.4 times before scratches and disinterest attrition it away.
Hardcore gamers will pay more for a console with more guts, and it's an entire separate market from where Apple is targeting. This has always been true. In 1983, hardcorers discarded Atari 2600 shovelware and spent billions of quarters in arcades. In 1993, they let the plebes have their Genesis/SNES while they bought a Neo Geo. In 2003, they modded and tweaked their Xboxen and bought immersive deluxe controllers and accessories for costs approaching that of another console (Steel Battalion, anyone?). In 2013, they'll buy the X720/PS4 and play Hero's Duty 7 with glee while one hundred million proletarians have a blast playing Sugar Rush 2 or Rock Band 5 on the ATV4.
