Index filed for "civil rehabilitation," a form of bankruptcy under Japanese law, in late June. Plans to sell of its operations were announced in mid-July. At the time, an Atlus representative assured Joystiq that its upcoming release plans would be unaffected. The publisher's latest game, Dragon's Crown – which we thoroughly enjoyed – should launch tomorrow.
A Sega acquisition would make sense, given that the company already distributes Atlus games in Japan. It would also help expand Sega's growing pool of talent – the company acquired Company of Heroes 2 developer Relic earlier this year.
