Only 2 stand out for me this upcoming season.

Blade of the Immortal
The manga was freaking awesome, i so cannot wait to see this series animated.

Slayers Revolution
it's Slayer so there really isn't much more to say on the subject.

the rest of them seems pretty meh and from the manga Sekirei is just another Ikkitousen clone so nothing special imo.

oh and the TTGL movie will be good but that doesn't actually count a new series but i'm hoping to be surprised by a few.
