RUMOR - Persona Q: Shadow of the Labyrinth sequel incoming?

Could a sequel to Persona Q be in the works? While Atlus hasn't made any official announcements, some internet snoopers found something interesting. The domain pq2.jp is now on the nameservers Atlus uses for their websites. Why bother doing that if there's not something to announce for the series? Now let's seen if this bit of fan sleuthing turns out to be spot-on.
