A release of the OUT is inevitable. I'm sure most people in Lucasfilm would've loved to see the OUT released, Rick McCallum included, but they didn't want to question George. Now that he's gone I'm sure it'll be released, especially with all the buzz we've been hearing about it everywhere.
EDIT: People involved in these films are even saying that the SE's were detrimental to the story of the originals, and that's really saying something. Imagine if PT actors said that?
