I asked Yonkou Productions about this. It looks like Gematsu incorrectly assumed this was from Jump, and it was probably from Dengeki Girls' Style and the DO report that.We're kind of inferring here that the "June 9th" date is based on the next issue of Dengeki Girls' Style which comes out on June 9th. http://dengekionline.com/elem/000/001/724/1724413/ And the reason we think it's that magazine is because the blog Gematsu sources was posting info from Jump, and right before that about some games from the company Otomate, which were announced in this month's issue.They source this article http://ryokutya2089.com/archives/10115 from ryokuya2089. And he doesn't say specifically where it's from, just that it's news. But the last few posts were either from Jump or from Dengeki Girls' Style. Or as salromano said, it may be from Corocoro.
