It's been announced that last year's fan-service anime series Princess Lover will be getting a new OVA series later this year. Only thing is that the two-part OVA will be a lot more similar to the original PC game than the TV series was, in that it will be an adults-only hentai release. Pretty interesting, as it's pretty rare for a non-adult anime series to get an official adult sequel. As far as I know, Green Green is the only other series to have done such a thing.
A different anime studio & a different staff will be working on the new two-parter however, so at this point it's unknown if it will actually be connected to the TV series or not. As far as I know, the voice staff hasn't been announced yet, so we may even get new actors. The character designs will be done by Kazuya Kuroda, who's most famous for his work on Vandread and Spice & Wolf, but more recently worked on the character designs for the Aki-Sora OVAs. Speculation is that Hoods Entertainment will be doing the animation, who are currently working on Aki-Sora as well as Seikon no Qwaser. So essentially they're recruiting all the big borderline-hentai names out there to work on this title. A NSFW scan can be found after the jump:
