-I don't give a single shyt for the new Sentinels or the new Master Mold/Mothermold. Unless you're going to really reinvent the idea a la New X-Men's Wild Sentinels or Operation: Zero Tolerance's Prime Sentinels, leave all that in the past. Not going to count this detail out until I read Powers of X, though.
-The other really interesting idea (or potential idea, at least): Until I saw Scott interact with the Fantastic Four, I would have sworn up and down that this was the result of Nate Grey and Magneto's experiments with the Life Seed at the end of Age of X-Man. After that scene, I get the sense that, while this may be real, those two are exerting a lot of influence on the mutants's current status (and I wouldn't be shocked to see it resonate through Powers of X as well). If this is Hickman's card, I wouldn't really expect him to show it this early, but it could be a fascinating meditation on what a Mutant utopia would actually look like and how it would function (I'd expect Hickman to botch it). And if this is partially Magneto's creation, then there's a very fascinating parallel with New X-Men (among MANY in this issue): in New X-Men, Xorn was the most Xavier-esque version of Magneto possible, while here we seem to be getting the most Magneto-esque version of Xavier possible (power politics, explicit religious allusions, etc.). This is all stuff I'm quite interested in seeing play out, even if my cockamamie theory ends up being way off.
