I'd be watching for states trying to enact their own bans to replace the Fed AWB. This only because the anti's on the Mi. legislature are trying to get a Ca style ban here, which would ban even Mini-14's (the wording is something like, "any gun which has a barrel shroud which completely encircles the barrel and prevents the hand from being burned")!
Edited to add: Looks like this one will never seee the light of day, but they are trying.
