Atlus has opened a new teaser site in Japan, but not much else. The site contains the URL p-atlus.jp with a yellow background and Persona-style front. By the by, Persona 4 was heavy on the yellow. Are we about to see Persona 4 Portable announced? Considering the past three games in the series have now made their way to PSP - the second is releasing this fall in Europe via Ghostlight - we wouldn't be surprised. We hope so anyways.
