Indeed. The most likely outcome is that the Supremes will rule that the right protected by the 2nd Amendment extends to bearing arms outside the home. A permit can be required, but rather than requiring an individual to show "good reason," the state can only deny a permit for an individualized reason and will be subject to a high degree of scrutiny. Only the most restrictive of states would be affected by this, such as New York and Hawaii. Those states will respond with attempts to push the envelope of reasonableness (as Illinois did for a while), and depend on their up-to-now complicit circuit courts to permit it until the Supreme Court again, in 10 years perhaps, takes up an appeal.
