I'm going to be watching Koyomimonogatari and Kizumonogatari, but if you haven't been keeping up with the series then these obviously won't be as interesting. I'll also be watching Kiznaiver, which is TRIGGER's new project, and Musaigen no Phantom World, which is by Kyoani. I've also heard good things about Dagashi Kashi so I might give that a shot.
also I finished Owarimonogatari yesterday after putting it on hold for a while and the last two episodes were stellar. This season was solidly good but the last two episodes alone pushed it to a 9/10 for me. One Punch Man was also obviously fantastic but I think I'm also rating it a 9/10 - I feel like there's not enough in the show to justify putting it at 10/10.
