One's I'm definitely gonna watch are:
Toradora
Kuroshitsuji
Clannad After
Tales of the Abyss (Played the game, never finished it, also it's a good thing they're still using the same theme Karma by Bump of Chicken; it's totally badass)
Kannagi (Had read a bit of the manga and enjoyed it)
Gundam 00
ef - a tale of melodies
Kyou no 5 no 2 (Gotta love the 5th grade perverseness I guess?)

Ones I might be on the fence about;
Tytania (Space Opera, usually turns out either amazing, or falling between the cracks of mediocrity)
Michiko to Hatchin (Seems like a El Cazador de la Bruja clone with more flair)
Kurozuka (read the manga which had a good amount of sex, nudity, but was rather average)

And maybe I'll give each of the random gory, action animes a try like Jigoku Shoujo Mitsuganae, Shikabane Hime Aka, GA-REI -zero- and Linebarrels of Iron.

I read the manga for the latter 2, and they were OK. They seemed to have changed the premise in Ga-Rei, and Linebarrels is being directed by the art director that did the Gundam Seed character designs.
