Throughout this run, this magazine has definitely done it's best to get a lot of its manga series adapted into anime. It's only a matter of time until the next thing gets announced.
Happiness seems to have decent sales, they adapted the author's previous work Aku no Hana. I think it has good chances of getting adapted, the manga is really good, you should check it out if you haven't had the chance to. It's super trippy. From what I remember it sold 30-45k per volume.
To the Abandoned Sacred Beasts also seems almost certain to get an anime at some point. The manga is phenomenal, it has amazing art and it's pretty underrated. It also sells decently 40-45-50k per volume from what I remember.
Then there's Tomodachi Game. This one is also does pretty well from what I remember I think new volumes sell from 30k-50k if I remember correctly.
Tomodachi Game started in 2013, Abandoned Sacred Beasts started in 2014 and Happiness started in 2015. Let's see what happens. For now, anything else they have in the magazine is either too new to be adapted or has already been adapted.
