As I understand it. Emma makes the offhand comment of wishing that she was never the Savior. Queenie overhears this while in possession of the lamp, and uses a wish that basically goes "I wish for Emma's wish to be granted". So, this AU is probably more of the Emma not being the savior, though there look to be elements of no Dark Curse as well. Particularly since we are getting things like Stealthy's return.

So while I don't have any definitive answer, my hunch is that it may actually be elements of both (Emma not the Savior and No Dark Curse).

Now, an interesting observation. Based on the Promos, it looks like Regina manages to cross over to this alternate universe (and hence the speculation that this is where we might see Robin). So, if Regina can cross over, can others cross back. Could Stealthy (or Robin) return to the "Real World"? Or is this alternate universe something more along the lines of the Dream Realm where Rumple and Belle first encountered Gideon (which would mean that only Regina and Emma would be able return)?
