Cali seems to me to be the last real hurrah. Of course, I reckon the next challenge will be whether or not bass-ackwards states like GA will have to recognize those marriages. Should make for some fun political discourse over the next decade in GA.
An extraordinarily disappointing ruling in my opinion -- and as dsnation points out, the initial reactions seem to be glossing over that (even the right-wing opposition) treating it as being much broader than it actually is. But certainly not a bad thing that when resolved it all but guarantees a return of SSM to California only.
I think this case has been derailed as the vehicle to obtain SSM at SCOTUS; it will be appealed, but I'd guess it's denied cert (affirming) or affirmed without comment and Ninth Circuit ruling stands.
Next up are the DOMA cases -- decisions on those are due anytime now in the 1st and 3rd circuits -- potentially more explosive in how they may impact federal recognition of same-sex marriage in states where adopted.
But, LOTJ, if you're gay, like me -- well I fundamentally have a problem with my basic civil rights being a political hot-potato for the next 10 years. As part of a bi-national couple, this directly impacts me and is the reason I'll be moving permanently to Spain in all likelihood.
