So looks like Marvel just announced Betsy and Rachel will be joining a new team in the new era.
Weird way to drop a pretty big info, but here it is:
https://www.marvel.com/articles/comi...l-summers-lokiRachel Summers, AKA Askani, currently playing a pivotal role in Krakoa’s final battle in RISE OF THE POWERS OF X. She will star alongside her girlfriend, Betsy Braddock, in a yet-to-be announced X-Men title in the upcoming FROM THE ASHES era.
From the titles we know, I think it could be X-force.
But I'm hoping that they're actually reviving Excalibur under a better writer.
