I think that the Court pretty clearly indicated it will support an individual right to bear arms. it also is probabyl going to permit some restrictions. The amount of restriction is of course the question. D.C.'s ban on functional firearms seemed to be seen as overly broad in any case, but I could only be trying to read tea leaves.

Edit. One commentator I've read about predicted: "As it is though, under any possible construal of “reasonable regulation”; I would expect that the majority of the gun laws in California, Massachusetts, New York, Illinois, New Jersey, and Hawaii; would be in whole or in part, struck down."
