Might be a bit premature, but there's already an anime map out listing a bunch of shows that are slated for Fall. I'm sure it'll get updated when the season gets closer, but still worth a post I think:
Spoiler: show
Magi S2
Kill la Kill
Yozakura Quartet (original anime was meh from what I've heard. This looks like a retelling of it, so it might be a nice change)
Yowamushi Pedal (looks interesting >_>)
Kuroko no Basket S2
Nagi no Asukara
Golden Time
Daiya no A (fuck yes! Love the manga!)
Not to mention a Chihayafuru OAD <3
Season already looks much more promising compared to what Summer has offered (for me at least. I know a few people are really enjoying Summer season)
