Those sets sell great in China. I think it's smart that MK is online only in the US. They just take up valuable shelf space in US BAM stores.
There were similar arguments on here about Sydney Opera House, Taj Mahal, Tower Bridge, European soccer stadiums and so forth. Unless you're an expat from that country or in that country, who in the US actually wants to buy and display that set?
I remember when the complaint was that some sets were only available in their region, making them expensive on the secondary markets. 80101 and 80102 appreciated quickly, but when 80103 became available everywhere, its value stagnated and eventually it sold at a discount.
I mean, I think the lessons learned for us brickpickers is 1) low or no ROI. Better off investing elsewhere, and 2) wait for the (likely) discount if you want them for yourself.
Probably like several of you, I thought the guaranteed short shelf life would make them appreciate in value quickly, faster than a Winter Village set, but I'm still sitting on year of the lion, rat, ox and now rabbit sets. I may have to seriously consider the suggestion above to remove them from my inventory and part them out into my bricklink store.
