The Tales of Hearts R official site has now fully opened, complete with character descriptions, new screenshots and artwork.
And it seems they're really sticking with the "Re-imagination" theme they started with Tales of Innocence R. This game is officially a re-imagination of Tales of Hearts. And the official art in the site's Story page is the same art used in Tales of Hearts' official complete guide.
And sorry for the delay on this one. School.
Tales of Hearts R will be released for the PlayStation Vita sometime Spring 2013.
