I wouldnt worry about them saying "under consideration", they say that with every new figure they show; happened with ssj Vegeta back when he was shown as a prototype. As long as we make enough noise about wanting them they will produce them.
As for the apparent size issues; Dont worry about that either, figuarts are always perfectly in scale, they wont stop now. Most likely it just because of the way they are posed and their position in the case.
Finally, android 18s arm joints are simply on back to front, hence the awkward monkey look. That will be fixed if she is made available.
