Confirmed per this official trailer, volume 8 of the Light Novel is being released on 2013-04-25, and the first 7 novels are being re-released subsequently. It looks as though the series is getting a new illustrator (and a new logo), though, which I guess isn't so surprising considering the publisher changed. (I wonder if the re-releases will feature all new illustrations?)
Volume 8 will also include a special DVD with some bonus features (no new anime announced at this time... but I have to guess they're heading that way).
