Hopefully they'll finally clarify the original and full intent of the 2nd Amendment. According to this article there are 2 pending SCOTUS cases that may address the issue.
The NRA petition can be read here (PDF).The Supreme Court in 2008 made it clear that the right to “keep” a gun is a personal right, and that it means one has a right to keep a functioning firearm for self-defense within the home. But it has refused repeatedly since then to take on the question of whether that right exists also outside the home. If there is a separate right to “bear” a gun (and the Court, in fact, did say in 2008 that the two rights were separate), it has not said what that means…
In a case from Texas, the NRA’s lawyers have reduced to elementary constitutional logic the question of what a right to “bear” guns means: “The explicit guarantee of the right to ‘bear’ arms would mean nothing,” the NRA’s filing argued, “if it did not protect the right to ‘bear’ arms outside of the home, where the Amendment already guarantees that they may be ‘kept.’ The most fundamental canons of construction forbid any interpretation that would discard this language as meaningless surplus.”
