According to Moonphase, CLANNAD TV will be airing on October 4th, on stations MBS, CBC and BS-i. Opening song will be 『メグメル -cockool mix 2007-』(Megumeru ~cockool mix 2007~) and the ending song will be 『だんご大家族』(Dango Daikazoku). Lead guy Tomoya will be played by Nakamura Yuiichi, a relative unknown for me.
Well, confirms my suspicions all along. Despite what many lay claim that Haruhi II will be airing after Lucky Star, obviously CLANNAD TV will be first, since they announced first.
Anyways, looking forward for more twins, the Fujibayashi twins are practically same as the Hiiragi ones, both in archetype and in style as well :D.
