I'm actually happy to hear that this won't be in HD. At first I was incredibly excited, then when the Wampa shot came out with the (no offense, Ady, you'll see where I'm going with this) awful new "tusks," I started to wonder. Then Ady said it was hard to find HD-quality stuff to work with for that shot, and I started hoping the project would revert back to SD - after all, I don't give two shits that ANH is SD, it looks fantastic, and I'm sure there's a lot more he could have used for that shot if it were done for SD.
If keeping it SD improves the quality of the changes, by all means, I have no qualms at all about it. In fact, I'm glad.
And I can't wait to get this in my DVD player to see it.
