I gotta agree with you guys, Nocturne still looks amazing, and their new game sure could use it as inspiration.
But even with its "more realistic look", than Persona at least, it has a style (which I'm not complaining, just pointing), and my main point is I do hope they don't try to too much to make them look "real" but end up making them look generic.
For example, Nier while it doesn't look as bad as people say, has some generic looking characters. Much worse could be White Knight Chronicles.
I think I'd rather want some characters looking like Atelier no Totori (from what has been shown so far), which isn't great, but has its own style, than have some cheap generic version of characters that have higher resolution.
Now if they could have characters look as real as FFXIII but a little less "happy", that would be awesome.
But don't take this the wrong way, by FFXIII, which I love those characters in this game, in the next megaten I mean the quality of the characters expressions, they almost feel alive,(like also in mass effect 2).
Quick version: I don't mean the "character design", but the possibilities of the characters expressions.
