Next season in yuri (subtext):
Brave Witches: Like Strike Witches, but brave. Seriously though, it's following different characters but has the same staff
Flip Flappers: Heavy Trigger inspiration aside, it's a magical girl series about a pair of close friends. And it looks like there might be some sort of fusion aspect to the transformation? They switch hair colours, at least
Girlish Number: Maybe. It's about female idols but there is a notable male presence and the writer is best known for Oregairu
Idol Memories: Seems to be aimed directly at older Aikatsu fans, who tend to be into yuri. And it doesn't have much of a male presence
Long Riders: Seems to be a CGDCT anime with more bicycles. Be pretty surprised if the lead didn't get subtext with her childhood friend
Lostorage incited WIXOSS: More WIXOSS, focusing on a pair of girls this time. On the other hand, the PV makes it look like there's significant male presence. Staff is pretty different from the earlier series
Magical Girl Raising Project: Maybe? Don't really know much about it. No male presence to speak of, though
Shuumatsu no Izetta: This one is partially selling itself on being yuri-ish. And, hey, variety
Soushin Shoujo Matoi: Magical girl, childhood friends, etc. And the director seems to like yuri
Stella No Mahou: Season's requisite CGDCT series. Has the director of Non Non Biyori, so it might be worth watching even if it turns out low on yuri
Vivid Strike: It's a Nanoha series... which have never been anywhere near as gay as the fandom would have you think. Not sure if it's going to be any good, either; the PV was worryingly low-budget and the director is a poor choice (great at comedy but poor outside of it, and this looks fairly dark)
SB69 and Eupho sequels this season, too, and we should be getting more Regalia around the time the season starts. Also, Gundam (not yuri, just awesome)
