Well, here's what we know about Magic coming up: they are going to Dominaria for the next two Sets this year,with the first two sets next year tying into those and involving Time Travel big time as well as Phryexians [Borg-like cybernetic Demons, for non-Magic folks] to some extent.Oooh, that's a good call. I think a D&D/Phyrexia crossover is quite unlikely, but yes, that would rock.
For everyone here who is unfamiliar, Phyrexia is a plane teeming with evil bio-mechanical horrors who are bent on invading and conquering all other realities. Picture endless armies of demon-machine cyborg monstrosities. Kind of the Borg plus Spelljammer but filtered through Tomb of Horrors a hundred times.
Yes, I would buy that.
They also have a "Magic Multiverse" art book covering all their Settings dropping for Christmas.
So, if there is a Magic Setting immenant (which is always probable now), then Dominaria is a likely possibility....but.maybe also a Magic Multiverse type book, covering Planeswalkers in Magic terms similar to spelljammer or Planescape.
