Atlus has officially announced the PSP remake of Persona 2 Eternal Punishment (appearances in Weekly Famitsu and on Famitsu.com don't count as "official" announcement). Access the game's newly opened teaser site here. The site will get its full opening on the 8th.
The Persona 2 official blog was also given its first update in about a year. The blog post shares some of the info from Famitsu, but also teases additional announcements to come. In particular, the post hints that there's something special about the game's illustrations.
For a first look at the game, see this story.
