It's titled Dôbutsu no Kuni (Animal's Country as far as I can tell) and it'll be running monthly in Bessatsu Shonen Magazine, with a preview chapter appearing a few days earlier in Shounen Magazine.
Additionally, he'll be doing three more one-shots in various magazines through September and October.
First is Aosora, in Gekkan Shounen Magazine.
After that is Oyaju~ Rider, in Young King Ours.
And the last one is Class Room, in Jump Square.

That being said, would anybody be interested in these being covered here as they come out? Thought it'd be a good way to get the community a little more active again.
