The "R" in Tales of Hearts R stands for re-imagining and Namco Bandai made a bunch of changes when bringing the game to PlayStation Vita. On the presentation side, Tales of Hearts R has 3D models instead of sprites and full voice acting for the main story. Namco Bandai also made over 10 new anime event scenes for the PlayStation Vita version.
Battles are in 3D too. Tales of Hearts R has a new system where you can chase enemies in the air and keep your combo going.
The game has a field map now instead of the dungeon roads that connected the world in the DS release.
Calcedny Arcome who was a NPC in the DS version is a playable character in Tales of Hearts R. Even when he was a kid, Calcedny was a skilled swordsman. He became the commander of the Crystal Knights and a follower of the Baraya faith.
Tales of Hearts R is slated for release in spring 2013.
