Am I the only one thinking about the M'Kraan Crystal in that image?[/QUOTE]

That looks like M'Kraan crystal. If it is then maybe the X-Men can choose their own individual reality. The promos we've seen show them either looking like mash-ups or depicting them from different eras. Maybe they get to decide who they want to be based on who they were. For example-Scott and Jean's costumes. Maybe Scott wanted to combine his revolutionary red costume with the more heroic blue and Jean wanted to go back to a simpler time before all the Phoenix stuff. I mean, she did turn it down in "Phoenix Resurrection."
