Famitsu has a follow up report for Tales of Hearts R which announced key staff behind the Vita re-imagining. Hironori Naoi is the game’s director. Ryuji Odate and Mika Murakita are listed as producers.
The Tales team redesigned the combat system and added "chase" mechanics. You can continue a combo in the air by flying towards an enemy using Chase Link. While you’re in mid-air, one of the ally icons might blink. Tap on them to do a Chase Cross attack. You can also do a Chase Finisher by holding down the attack button.
Tales of Hearts R is slated for release in spring 2013 on PlayStation Vita.
