In regards to the OP.....
Sephiroth has run his course, sadly. Although he still retains some sort of power in the lifestream, I don't honestly see how he will be able to come back to do anymore damage to the planet, unless he does it directly from the lifestream instead of using a catalyst like he did in Advent Children.
And how they intend to revive Aerith and Zack?.......Yeah, not gonna happen, unless they throw logic and balance out the window just to revive the compilation. Let's face it, Sephy is finished. Even he himself knows it. Cloud has finished his job, and is done with his role.
