Anything by Ao madousi. I've recently found out about him and I can't believe how hot his works are. Like, for real. Instantly shot up into my top 5 list. I often find myself checking to see if he has any new works out.
Does it have to be a hentai movie/ova?
If anything, I'm waiting for the English translation of Hisasi's latest tank. The compilation of amateur translations is just horrid, especially from "One of a Kind" translators.
ha? Pink Pineapple never was a studio, because it never produced a single animation, it is just a label of the publisher Softgarage. As well as Mary Jane is no studio, it is just a label of the publisher Dagdag. Only T-Rex in your list is a studio.
And the thread clearly asks for an UPCOMING animation you are waiting for, not for just common phrases without specification.
I'm super exited for - Muramata-san no Himitsu - by Queen Bee. I read the source doujin on nhentai and I gotta say, the split tongue thing is really arousing.
