The question is, will they spend the money for a truly first-class restoration: using all the best sources available, bring in the top restoration experts, blank check, take all the time they need to do it perfectly, etc.?

That's what *should* be done, and even with the expense, it makes sense to protect and restore these films to the nth degree. It would be utterly foolish not to do so. They just spent a fortune to buy Lucasfilm, and to not protect the most valuable thing Lucasfilm has as well as it can possibly be done, would be a huge loss even from just a business perspective. But that doesn't mean they *will* do it...
