The other possibility, of course, is that there may be some interesting ballot measures in the very next election. Gerrymandering might become fashionable 
You mean making the 49 60% Obama districts map a 2016/18 proposition of its own? That would be hilarious, but I have to think it would never pass. Then again, Maryland voters upheld their map by a wide margin in a 2012 referendum.
More likely would be new initiative in both states for Washington style commissions where the state legislature picks all of the members, but they are evenly split by party, and they have to make a deal.
This all assumes that the Court doesn't strike down the entire initiative/referendum process on anything related to redistricting, of course.
What I mean is that framing could be important. If the SCOTUS decision in AZ case is framed as partisan, then the partisan political response is possible - probably, in fact. At present Dems increasingly feel (correctly or not) that they are being screwed by the gerrymanders in Republican-controlled state. That CA (the largest state, and the one they have control of) actively prohibits gerrymanders, might start looking as stupidity, rather than virtue. And the state has a sufficient Dem preponderance that, who knows, abolishing the virtuous stupidity might actually pass.
