I wonder if it's too early for them to give a breakdown of the differences between the PS4 and PS3 versions? Japanese companies tend to be upfront with announcing the differences. Square recently released this list for Dragon Quest Heroes 2

I hope the difference is big and very noticeable. I want my PS4 version to look very clean of aliasing and shit.
