Glorious news! Wouldn't surprise me if Georgia is #50, if only because it was (I think?) the last state to have a court case filed against the ban.
That would be Nebraska, not Georgia.
The fifth circuit will obviously issue a stay, and seeing as it is more conservative than the 6th circuit, it will likely rule in favor of traditional marriage for both this and the TX/LA cases.
It's possible, but it's also very possible that the 5th Circuit will make it legal in all 3 states. Remember, it's not really a liberal/conservative thing anymore, it's just a matter of "Do the judges take their jobs SO unseriously that they'll let their personal bigotries override a very obvious legal decision?"
I have faith that the 5th circuit will do the right thing. Mainly because it's more like "I have faith that the 5th circuit won't do the egregiously wrong thing," but it's all the same.
