As random as this may seem, my very first thought was, "It's a shame they're getting rid of Magik's redesign." I really liked the gold and thought it was symbolic for the development she received in New Mutants. Oh well. As for what we've learned about the new direction, it's not what I was fearing aka 90's nostalgia overload. It seems more like they're trying to go in the diametrically opposite direction of Krakoa: whereas before mutants were united and living together away from humans, now they're all separate and living amongst humans in normal, real world locations (Chicago, Louisiana, Alaska). I don't know much about the creative teams (I've only read one book by Simone, and none by MacKay or Eve Ewing) so I'll leave that to others to discuss/speculate.
As always, I will hope and pray that Angel pops up at some point. He's not going to be in the core books, but there's still a chance he might be in one of the satellites.
