I mean, based on the solicits Ewing will be dealing with In-Betweener first.
Since Hickman intends to revisit GODS; presumably they aren’t marked for death or limbo like other IPs; there are probably limits to what Ewing can do with them.
At the very least it will be some less than subtle railing about making the very foundations of the marvel universe even more corrupt that Oblivion has a say in things, and Loki will probably take down Wyn with a lecture or two, while Taia and Blue Marvel deal with what’s left of the Centum. Odds are LT’s reduction will be explained as a consequence of his death in Ultimates?
Edit: the above is not a knock on Ewing btw. As noted he’ll inject much needed emotion, but there’s only so much he can do, and Hickman’s themes are squarely in stuff he rails against
