Ok, first of all, I'm not sure where this should be posted. SoA seems to be the best place to put it, if it isn't then I'm sorry.
When doing my own EE research I found that a German speaking player had posted a playthrough of what seems to be 0.8.9. From Bastion to Earthrise (the last quest they complete is "The Anubian Warlord").
As far as I could tell this is a complete-ish walkthrough for the islands. I think it's a rather rare set of footage.
