That I am actually watching, from before:
Claymore
Hayate no Gotoku
of any others from last season, I'll probably try to get around to watching Lagann.
As for new ones I decided to check out:
Sayonara Zetsubou Sensei
Code-E
Baccano
Zetsubou Sensei is hilarious, Code-E seems just decent, and Baccano only had one episode out, but it was fucking epic. A bit confusing, but for some reason it gave me Pulp Fiction vibes, and I loev me sum Pulp Fiction.
