indeed lol
There is higher resolution textures but that's about it, aside from 60 FPS.
Not too surprising since it looks to be a port. I still do think though that the first PS4 shots shown looked really nice. I imagine there's a noticeable difference when you're not watching it on youtube. Though, probably not such a big difference that it's going to make people run out and buy a PS4, but it's a nice bump in eye-candy for existing PS4 owners/people planning on getting a PS4.
Hopefully the next Yakuza game uses an engine that shines on the PS4.
