I hope Sony is taking their position in the gaming industry more seriously than you are. Let’s revisit this conversation in four years when they fall short of PS4 sales, even with less competition from Xbox.
By the way, there's a significant fanbase that stuck with PlayStation mainly for Japanese games. Do you know which console is now better suited for that fanbase than PlayStation? Here’s a little hint: it’s not Xbox.
Do you know which other platform gets the same amount (or even more) of Japanese games than PlayStation? Here's a little hint: it starts with a "P" and is followed by "C".
So yes, there are alternatives, and asking too much from their loyal customers could really lead to their downfall. At least their console side of things.
There are other big companys who fucked up big time and who have big problems nowadays. So nothing is set in stone.
