From this TV/ONA airing list I'd say I'm most interested in:
Jormungand S2 ------------------------ I thought the first season was alright.
Chuunibyou Demo Koi ga Shitai! ----- sounds interesting
Busou Shinki TV ----------------------- I liked some parts of the ONA. Hopefully I'll like the TV series more
Onii-chan Dakedo Ai Sae Areba Kankei Nai yo ne— ----- yeah, I know...it's another Oniichan anime. I think this was a novel.
To Love Ru Darkness ----------------- the manga is mostly about the nice art and massive ero fanservice, but it does have some plot to it. It's not for most people.
Haitai Nanafa ------------------------- hard to tell if I will like this
Little Busters! ------------------------- Lot of people really liked the game.
Code Breaker
Ixion Saga DT
Sakurasou no Pet na Kanojo
Girls und Panzer ----------------------- wasn't interested in reading the manga, but maybe I'll like the anime version
Robotics;Notes
Seitokai no Ichizon: Shin Anime (Kari)
Psycho-Pass ---------------------------- with that Madoka writer working on this who knows where it will go. Psycho stuff is good.

Jojo's Bizarre Adventure TV ----------- I still have fond memories of the first OVA. I'll give this a try.
Btooom! -------------------------------- I like the manga, but I'm sure the fanservice will turn some people off.
Initial D Fifth Stage
Shin Sekai Yori
There are other anime that could interest me, but it's hard to tell if I will like them until I actually view them.
What are you most looking forward to seeing?
