I suspect we'll see new renders of Mila for chapter 1 - her hair there is the only legacy asset I can think of that remains that is maybe important enough. It also sets the tone of how people see her. I suspect Ocean will have redone those and fixed his sculpt tool error by the time we see S1 full and give us a more consistent Mila - actually, as long as Ch1 Mila disappears, I'll be happy
I'm fine with every other version. He's probably not gonna say if he does do it, just spring it on everyone, given the face palming he'd be receiving if he announced it. Pure speculation, but I think it'll happen just to get rid of that very obvious low res asset.
