Falcom is readying a new entry in the "Kiseki" series for PSP. Revealed during a shareholders briefing today, the new game is titled Nayuta no Kiseki. The game is due for release in 2012.
A slide shown during the briefing (and passed along at Falcom's official Twitter) also lists two previously announced PlayStation Vita titles, Ys and the full voice version of Legend of Heroes Zero no Kiseki. The Vita version of Zero no Kiseki appears to have a new subtitle which is blocked out in the slide.
