Legend Studio Display Cases?

[Newbieguy]

I have two normal size case and was going to pre-order 2 more today, but now I don't even see the normal size available for pre-order? Why are these cases so hard to get hold of and keep some in stock?

Will sideshow get any more of these normal size in stock?? If not, I am kinda screwed because without 2 more my display will be incomplete.
