I can say this, at least: There will never, ever, ever be an official semi-specialized at least not intentionally. What I mean by this is they may fuck up an OUT restoration and inadvertently keep in SE elements (like the recomped speeders in ESB). But there is absolutely no reason to release a semi specialized version. There is much less market for that than the OUT. That also spits in Lucas's face much more than simply releasing the original versions- it would be denying him final cut privileges.
