There's no japanese style games on the near horizon to get people there pumped. And I'm in the same boat.
I currently have the White Destiny bundle preordered, and outside of the indie games on PSN, I don't see much that I would want to play on it(from what is coming out this year). The games I'm most interested in are the same games that I bought a PS3 for, KH3, FF15 and Last Guardian. And we still don't have confirmed release dates for any of them.
Games like Uncharted, Killzone and Last of US don't do much for me, I don't see them as system sellers, especially in japan. Metal Gear is a joke of a series now, no matter how good it looks. Knack and LBP are trash. And there are no JRPG's or "weird fun type" japanese games (Katamari/EDF 2025) coming out this year or in the near future.
Meanwhile PS3 has Xillia 2, KH:HD2 and Akibas Trip coming out this fall. And as far as we know Persona 5 is still PS3/360 only.
No Man's Sky isn't out till next year at the earliest.
So like post Japanese publishers and gamers, I don't see a reason to drop my ps3 any time soon. For what I want out of a system the PS4 isn't there yet. Is ps4 going to be like the PS3 where there's nothing I'm interested in till it's 3rd year?
