Came across another person on Twitter connecting Genesis and/or Loveless to remake as being significant, and I think these people are on to something, so my new prediction with their concepts:
FF7 Remake Part 2: The Desolation of Cloud
Genesis is writing/remaking the events of the original story, just like the final part of Loveless! Sephiroth is his 'muse', which is why he's locked away in a place specifically known as the 'apex of creation'. He needs Cloud's help to escape. Meanwhile Genesis now is very fond of Zack because Zack basically saved him and his soul in CC, so Genesis 'rewrites' his fate, for him to survive instead of die. Sephiroth, however, is finding ways to fight back using the whispers. Aerith has been sent in as a kind of secret weapon for Genesis, to encourage changes and to stop Roth.
This whole remake is a fight for the soul/direction/story of FF7 itself. It's a narrative war!
