While the short blurb is beyond my limited Japanese knowledge, there is mention of the 30th of May. I'm doubtful that will be the release date, though there's the possibility that we'll see some more information being released on that day.
Though there's little more to say than that, we'll let you know of any developments. Be sure to check out the slides captured from the conference over at Gemaga 1985. With Dissidia and now the first two Star Ocean games on the way, it looks like RPG fans are going to have a tough time putting their PSPs down.
PS3 owners, be sure to check out this post over at PS3 Fanboy for more Square Enix news.
