It would be nice to hear from Lego that they will review the builds and revise them to bring them up to normal set production standards like they do with the ideas sets. The older waves like Castle in the Forest did not have the Lego logo on the box but the next wave did and there are still build issues. For $400 we should be getting a top quality set with a structurally sound build and high end minifigures, but unfortunately that is not the case.
We are paying almost $0.10 PP for these sets that come in generic flimsy warped boxes, mismatched minifigures, and without instructions, at least the build could be structurally sound. We should expect more from Lego at these prices, but yes to answer your question I will be buying the castle tomorrow for personal to build.
I think these all have a strong potential to flop as an investment with the increased production number to 30K and the limit of 2, or perhaps I am way off as usual I just don't know.
