Those were the words Atlus told news sources when asked about plans for 2012. Most fans, myself included think it may be Persona 5. They started work on it not long after P3P was released and while the Vita port of P4 and Catherine have been keeping the team busy, there is nothing to say they haven't been working on it on the side. Besides, announcing the game doesn't means it will be released this year, but we may get to see some screenshots and hear some new info on the title.
The other title fans are expecting is a console entry for Shin Megami Tensei which is also plausible but I feel P5 has this in the bag unless there is some other high profile title Atlus has the rights to that is escaping my mind at the moment.
So any thoughts?
