The Engrish from the source Japanese link is pretty bad. Does Index own Atlus or Is Index Atlus' name in Japan? If it's the former I hope Sony picks up Atlus quick if they get sold off.
Index is atlus's parent company . So yes it's the former. Also atlus made a statement saying this will not effect games already announced but may affect games in development. Which I take to mean bad news for persona 5.
