The BEST case scenario imo would be reaffirming that the 2nd amendment not only applies to "the people" as individuals, but ALSO that "the people" are the militia, not just the NG. In the opinion they would also mandate congress to update the militia act to modern wording and equipment thereby enforcing that all households would at least have one serviceable battle rifle and ammunition.
Worst case would be that only the militia can have weapons and the militia is only the National Guard clearing the way for federal and state governments to ban all small arms from the population.
What we will get is something in between I think. The right to keep and bear arms is with the people, but city, state, and federal governments can ban individual weapons by name, but not class. Unfortunately this will still clear the way for AWB II to pass with some minor changes to prevent overturn.
