I think I read somewhere that there was not going to be a New Game+ but it will will feature a EX dungeon exclusive to this port. (Which I hope will be very challenging)
Yes theres a new game plus but to explain what it adds would be a spoiler so all I can say it's worth playing again.
Well there is the multiple difficulty hack.For the 3DS version they added a few "hacks" can change change difficulty from easy to Hard and eliminate alignment demon limitation (like in SJ), among other things.Also I think the EX dungeons are basically the "NG+" content.
