[Update: The commenters have brought up a good point, that this could also be a PSOne Classics release and not a localization of the Japanese PSP version. Of course, we'll let you know as soon as we do.]
Another of those attentive folk at NeoGAF has spotted a new rating for Persona 2: Eternal Punishment at the ESRB's website. This is presumably the version which released for PSP in Japan last year but has yet to be announced for North America. This is a very clear signal that the situation may be about to change. Make whatever preparations you feel are necessary.
Meanwhile, weep for the people on eBay, where copies of the original PlayStation release of Eternal Punishment are listed in the neighborhood of $100. Remember that the wider availability of desirable games hurts them and their families and weep a single tear when you make the purchase of your shiny new copy.
