So far Washington is the only one that has been formally reversed, although a couple of others (Morton Grove?) took the hint and dropped theirs. Heller only applied to Washington; the Chicago case will establish if the Second Amendment applies to just the Federal government or to State & Local governments as well. It is expected that the Second Amendment will be incorporated to apply to all levels of government. Once that happens there will be a flurry of lawsuits against various State & Local laws.
