Jay,
The ruling yesterday was about the Equal Protection Clause of the Fourteenth Amendment and the Due Process Clause of the same.
That's all. The Bill of Rights was initially criticized because of the inherent problem in enumerating the rights of the people. If you list rights then some idiot down the road will get the idea that people only have rights that are listed. No Bill of Rights captures all the rights of the people. Unless something is specifically denied to us as part of a grant of power to the government then it is reserved to the people. As in its not surrendered.
So in the future, constitutional law especially in the area of fundamental rights of citizens will continue to seem to be "expanding" when in reality we are only recognizing the inherent rights of people and applying them to different situations.
Gays have the same rights as you and I. In every way you can imagine that. There is no way that one person in society can hold a right that another person is disqualified from holding and enjoying without the due process of law having properly deprived him of said right.
