Again, while I appreciate that you enjoy the books and want to see more, please understand that scanning isn't done by an organization.
If someone had them and was planning on scanning them soon, they would have said so. They haven't, so there's no schedule. Someone we've never heard of might post one elsewhere that makes its way here tomorrow, or it may never happen, if nobody involved in scanning has an interest or access to a copy.
It's a lot like asking "when is someone going to write a comprehensive book on Don Quixote's resemblance to the Friulian Benandanti?" It might happen immediately, but it might not, depending entirely on the interests and resources of writers. And asking over and over again (without contributing to any other conversations) isn't going to make anything happen fast. It's not exactly polite, either.
