I played the PS3 version for about a half hour, and here are some brief, mostly technical, impressions:
-Loads aren't bad at all, in fact I could easily play through the game as-is (though I'll gladly take a patch to make things snappier). They range from 3-10 seconds thus far, but exiting a battle has been near instantaneous. No loads for the menu open/close either.
-There's some occasional choppiness in loading dialogue or scenes. Nothing major, but it does give the game a decidedly low budget feel.
-I really like the look of the game. The graphics are simple, but lovely. I enjoy the anime character designs too. Overall the game is a huge step up from the older games in terms of graphics. From what I have seen the PS3 version is significantly higher res and has more detailed character models than the Vita version. The framerate has been a pretty smooth 30fps for the most part.
-The battle system is wonderful thus far. Much like the older games, but it looks and feels a lot better. Very snappy pace too.
-Lots and lots of voice work, which is really nice.
Overall I'm quite pleased!
