That isn't to say it isn't a New Gods thing, but from what we've seen from future solicits, it doesn't seem to be that.
"Trapped in a technologically advanced dimension where magic is outlawed and magic users are hunted and executed, the team must find Zatanna and Tim Hunter within 48 hours or be trapped there forever!"
That would be a radical re-working of the New Gods, I think. Although I suppose the Mother Box could have been a separate thing that transported Tim there as a failsafe.
Lots of possibilities, and I am open to them all!
