I managed to get a hold of media blaster\\\'s email and send them one asking about the fate of the volume one dvd box for Genshiken volume 2. They responded in kind telling me that they do have pplans to release an ender box for the series. This means that the last volume in the series will have a case to hold the complete series. There wasn\\\'t any info about any possible extra\\\'s added in with the box but I thought it was great that Media Blasters responded to my email in kind.
On a side note to Genshiken I was also told that there were no plans to release the ova series (the same three episodes that were released in the Kujibiki Unbalance Anime) into a single volume at this time.
