Seems I'm late to the show but

Definite
Highschool of the Dead
Seikirei 2
Sengoku Basara 2

Probably
Sekimakutsu Occult Gakuin - Who needs more than thigh highs and a miniskirt (and maybe Ersatz Touma)?
Shi Ki - Doesn't seem to be much else serious this season.

Maybe
Legend of the Legendary Heroes - Silly name is silly but action is action.
Amagami SS - Sounds episodic and melodramatic, may be good on occasion.
Ookamisan .... - Sounds like a potential replacement for Daimaoh

Nurarihyon no Mago - Why not

Soap Boxing
Asobi ni Iku yo - wow To LOVE Ru got a reboot?
Seitokai Yakuindomo - wow Seitokai no Ichizon got a reboot?
