both Nintendo and Sony really need to push their targeted audience in Japan first to buy home consoles more than handheld. I know the gamers there are more 'on the rush' or get-go and wanted to play on the train/bus and anywhere they want. but home console experience, they need to capture that audience back again. once they've got that audience, japanese developers can really put a lot of games to the home consoles.
i really hope it would happen. but JRPGs to PS4 is a good start. Hopefully Wii U would also get its fairshare of JRPGs. Wii has a ton of JRPGs but no sequels aren't coming to Wii U that I know of, except XCX.
