Acquire’s localization list at GDC included Class of Heroes 2 with its name written in English. Their tiny cubicle area was decorated with a few Japanese promo posters too.
Of course, this news doesn’t mean Class of Heroes 2 and its flying sharks is guaranteed for North America. Acquire is just actively searching for an international publisher. Before you give up hope, know that Atlus was at GDC hunting for games to publish and they released the first Class of Heroes in North America.
