DC Gun Ban Unconstitutional

Drudge links to the ruling here and a different summary is available here. The crucial two aspects of this ruling by the DC Circuit Court 1) upholds that the Second Amendment addresses individuals rights regarding guns, and 2) asserts that the Second Amendment does apply to the District of Columbia. This is a very, very big breakthrough.

Would it be a good thing for this case to move up to the Supreme Court? How would the current Court rule?
