The main thing want to avoid is taking the time to recommend something you've already seen. With Spice & Wolf, Haruhi, Katanagatari, Bakemonogatari, Railgun & Kimi ni Todoke on that list, I'm gonna suggest you take a look over
my tracker profile. There appears to be quite a bit of crossover in our tastes (I'll forgive you for Deathnote & CANAAN

). If you've not seen it yet,
NOIR is something I consider to be a
vastly superior similar-to-CANAAN kind of genre, even if it's quite a bit older than your request.
Also, these four shorts come to mind; very entertaining and diverse, they're quite recent:
2010 Young Animators' Training Project •
