What I personally see is, they are working on everything else than finishing the set we already put our money a year and a half ago. I won’t preordering anything until I receive the stuff that I already preorder. Also it conflicts with the info above that they already work on too many projects that why there is a delay on the current preorders. I remember a couple years ago, they told us, there isn’t going to be a preorder option till the set is 2-3 months away from being released. You can throw that out of the window.
We are working on items that we can, we have NO control of the Chinese factory so instead of doing nothing, we choose to develop other items in the meantime. As you have noticed, we have not asked for pre-order on other items until “Amerika” and U.S. sets start shipping.
