All art is at once surface and symbol

I definitely wonder how they're going to handle the dub of the new Mewtwo movie, especially if it's a straight-up CGI clone of the first version. I imagine the old VAs are out, but for example - largely stick to the old script? Rewrite it entirely? I haven't really followed the Pokemon anime for ages (and only really know of the original version through others' reviews and a couple of used CDs in the first place), and I'm not sure if there's a precedent with old content being put out under the new studio.
