Your predictions are wrong. Prop 8 was overturned based upon a leftist judge ruling that the law was put in place by voters with no rational basis -the judged ruled that religion was not allowed as a basis for a citizen to vote.
The Supremes will throw out this leftist nonsense. DOMA has nothing to do with this.
You misread my comment. I said Prop. 8 will be upheld-- i.e., the 9th Circuit case overturning Prop. 8 will be reversed.
