Here, let me be a Futurist like Stark:
***POSSIBLE FUTURIST SPOILERS***
-Captain America will refuse the registration and go up to Canada to form the new Alpha Flight. Johnny Storm will be beaten into a coma, Sue will die, and She-Hulk and Hawkeye will join the FF. Spider-Man will reveal his identity, Grant Morrison's Marvel Boy and the Squadron Supreme will join the Marvel U proper, and Wolverine will still appear in every single Marvel book ever.
I'm a Futurist!
