Gravity Rush Original Storyboard

I found a picture of what the plot for GR was supposed to be, had it not been split into two games, and noticed a few things

Most of the events of GR1 play out as they show up here until the third row with a bunch of cut content, which was probably supposed to be the neu hiraleon missions

None of what happens in GR2 shows up here except for the eto chapter, does that mean 3/4 of the game is just filler?

Also I noticed the whole kat/raven being split from one person isn’t ever really explained how it happened, could it just be a reference to how GR got split into two games when it was meant to be one?
