Corvos-Garlean conflict will get special care, likely via Graha and the Twins. This is a clear loose end.

Strangely, I think it will be G'raha and Krile who will be on that story thread.

The Twins have their hands full with Garlemald; Krile repeatedly throughout EW expressed her regret at being stuck on the sidelines AND falling so far behind the other Scions (to the point even she feels like she'd just be a burden); and she gives off very "big sis" vibes with "Raha". It would be a good excuse to give her some TLC, and delve into the apparently close relationship she and our Catboy have a bit.

Ali and Alphi will be the Scions on the ground for the Garlemald issue. Estinian is yeah, likely our story-hook into the Meracydia expac (7.0). Then the New World (Thancred); Shard Travel (Y'shtola); and Space Travel (Urianger). Like, outside of even Emet's bucket list, the Scions themselves all seem settup for a swath of new stories big and small.
