Well... I don't have any impressions at all yet -- but here's what I plan to check out:
Sankarea
Status: 3 episode probationary watch, wondering what they actually plan here... dark romance?
Gakkatsu!
Status: 1 episode probationary watch (I like debate?)
Recorder to Randoseru Re
Status: Need to watch 1st season, I missed this one.
Natsuiro Kiseki
Status: 3 episode probation, mostly because the VAs make up the pop group Sphere and its an anime-original work.
Nazo no Kanojo X
Status: originally ruled this one out... but the artwork is interesting so if I can get beyond the body fluids o.O ... we'll see.
Haiyore! Nyaruko-san
Status: Its Cthulhu!!!!! I have to at least take a look.
Sakamichi no Apollon
Status: Unique premise demands a chance...
Hyouka
Status: I always try to give co-ed ensemble series a chance.
