As for what I expect out of the USSC... not much. They wouldn't DARE upset the apple cart as much as it needs to be. The CORRECT ruling would be that the 2A protects an individual Right against all infringement. Period. Not just for sportin purposes, not just for personal self-defense, but also as a last line of defense against government tyranny. As stated in several judges dissenting opinions. Due process in criminal proceedings is the only way to strip someone of their Rights, as explcitly stated in the Constitution.
What they will probably do is come up with a decision half way between what people like you want, IE; unrestricted power to ban firearms at the State and local levels, while still trying to maintain the fiction that they believe it is an individual Right.
Pretty piss poor Right if any little tin-horn Mayor can strip that Right from you wit hthe stroke of a pen. It's a top down system that isn't written in greek. Plain language "supreme Law of the Land" and "shall not be infringed" are pretty darn unambiguous.
Same old sourceless question begging.

Already scrambling for excuses.
