Not that it will make any real difference. This decision is coming from a three judge panel of the Ninth Circus, so we're already pretty sure how that's going to go. I fully expect them to declare a constitutional amendment unconstitutional.
Nothing will change regardless of how the decision comes out because this issue is destined for the Supreme Court. Until then, this is just a distraction.
UPDATE: As expected the Ninth Circus ruled Prop 8 unconstitutional. On to the Supreme Court.
Justice Reinhardt wrote the Prop 8 decision. He's married to former head of So Cal ACLU, so this decision certainly isn't a surprise. I believe Reinhardt holds the record as the most reversed appellate judge in history.
