According to a Japanese blog post on the Atlus site (via Dualshockers), the company could not make any announcement on the titles because of the bankruptcy of parent company Index Corporation. "As next year is the 25th anniversary of the Atlus brand, there were a few things we wanted to announce, but we need you to wait a little longer. All of the unannounced titles were still wrestling with are currently under 'earnest development'," Hashino said.
"Were just trying to figure out how to further better them. While weve been spending our busy days full of challenges, we'll do our best to work heartily and not break concentration!"
