Yes, the Alan Scott business was a mistake from the begining. But right now, the future of earth-2 depends of whatwill happen in Justice League and Doomsday Clock. Most probably than the Justice Society "official" or "mainstream" (I really don't now how to label them) will be the natives of earth-0, meanwhile earth-2 will be left into alimbofor thetime to come, until some editor give green light to work on the concept again, either to take the new52 earth 2 in a next step, or go back to something more close to the precrisis earth2, as was seen in Thy Kingdom Come.
You, sinner...
Bendis is already working on that. Check Young Justice soon.
