I still find it hard to believe people bought a PS2/PS3 just for the disc player, at least I don't know anyone who did and I think those not interested in games would probably find such a device confusing as a media player. It was never in the media player section of stores so they'd have to know about games and go into the gaming section, thus probably really only purchased by gamers. Sure, a few might have read some Internet article about it and you probably had a handful of hifh/home-theater geeks doing it, but I doubt that counted for many sales. And wouldn't those kind of sales where the consumer isn't going to buy a bunch of games are actually bad for Sony if they console was really selling at a loss? They'd never re-coupe that money from those people though game purchases.
Also, I still see people at the local shopping centre buying DVDs out of those bright green vending machines, not old people either, like teenagers and people in their 20s.
I die a little inside every time I see it.
I still also think you're putting too much stock in 4K displays. On the desktop and devices where you do a lot of reading and you're quite close to the screen, high-resolution density is critical. I have an iPad 4, love it. But for TVs displaying motion-blended frames from 10ft away... utterly pointless for anything under 80 inches. Sure 4K sets look great in a store, when you're 1 foot away from the bloody thing , but put that in your lounge and sit back 10ft - now unless you have much better than 20/20 vision you literally won't see half the pixels any more.
