So we've got the following courts of appeals hearing arguments in the near future:
6th Circuit- August 6
7th Circuit- August 26
9th Circuit- September 8
That means decisions in each of those courts ~3 months later. That just leaves us waiting on the 5th, 8th and 11th Circuits. We should at least get the 5th Circuit decision by the end of the year. At that point there won't be much left for the Supreme Court to wait around for.
States in white (and DC) already have legalized same-sex marriages. Other states are coded by district:
I do not know the status of SSM in Puerto Rico, the US Virgin Islands, Guam, or the Northern Marianas.

Colors have no political significance.
DC and all states within the 1st, 2nd, and 3rd circuit courts have legalized SSM.
