The way I see it, once the heartless ordeal is all done with, everything will turn back to normal, as if nothing ever happened.

As for the picture. The outfit looks a lot like Aeris's, so I'm gonna' assume it's her until proven otherwise. I mean, Sephiroth came back, why not Aeris?
There was no FFVII 'world'. They were all from (SPOILER)Hollow Bastion, including Squall.

And, yes, Sephiroth is back. http://www.rpgamer.com/news/Q2-2004/062004a.html There's some information, translated from the official site, on a lot of the main characters.

Tonight my friends and I made a sacred pact. If Aerith is ressurected or some similiarily stupid stunt, we're not going to buy AC. We'll download it, watch it, burn it, and generally mooch, but we wont buy it. *nods*
