*outlawauron links to a site providing exactly what kupomogli stated*  DLC that you can buy on the PS3 and a small dungeon with some extra bosses.  So where are the nice improvements?  Oh, that was it? 

You just spun to your argument. I think the dungeon and DLC is nice. I also think the event/cg viewer is nice. Not having to purchase separate DLC is also nice.

When it's digital and the cost of the Vita game is double what the PS3 game is, then what does it matter?  You're going to get the DLC digital on the PS3 and the cost of the physical copy of the game plus the DLC will be cheaper than the digital copy of the Vita game.  You're paying more to get the same thing.

I thought you've never played the game, how would you know the dungeon is nice.  An in game art viewer is nice?  Here's an in thread art viewer, where you could technically view all the same images so long as I found them and posted them, but I'm not.  All those images were probably online long before the game released and  I guarantee most people would look at them once and then be done with it.
