The Familiar of Zero Forum

Zero no Tsukaima, aka The Familiar of Zero, will air a fourth season this October according to Anime News Network.  The anime franchise following the adventures of tsundere magician, Louise Françoise Le Blanc de La Vallière and her summoned-from-Earth servant, Saito Hiraga began in 2006 with one 13 episode season and followed by two more each running 12 episodes long.  The most recent season aired back in 2008.  The announced fourth season airing this Fall will be comprised of "selected episodes" from seasons one through three.  A final season, presumably season five, was also announced although when that will air is still unclear.  It makes sense that a "review" season would air on TV before the finale.
