That was my general understanding poita, but I am glad that you clarified it just the same. I apologise if what I said lead to any confusion. I think by working on full scans on proper sources, like you are doing, your project is going to go a long way to fully preserve the original theatrical prints as best as we have seen or could hope for.
Now as to whether the X0 project comes back/still exists in some form, that would be an interesting discussion.
