Oops. Genshiken will NOT be 26 episodes, it will be 12 episodes, released in three boxes of three discs each, two episodes per disc, with the third disc being extras and a single uncut 25 minute episode of Kujibiki Unbalance. It appears that Kujian will thus be a three episode OVA, representing episodes 1, 21, and 25 of the supposed actual Kujian series. Further information here.
