I don't usually recommend flipping sets, but if there was ever one that cried out to be flipped, it's this set. As I have mentioned before, this set had all the signs of being a limited run. As time on though and I read responses from LEGO and from fans, I get the sense that LEGO could rip off another run or two of these sets, just to quiet any complaints.
The prices being paid for this set are now 5 times MSRP, which is fantastic. If any other set hit 5 times MSRP, people would be unloading them quickly. At this point, you have to ask yourself if holding onto this set is worth the risk? How high can it go? $150? $175? $200? Maybe. Maybe. Maybe. If LEGO has stopped production of this set and with the XMAS holidays upon us in a few months, there is no telling how high this set could climb. Many consumers will forget what the item originally cost and will pay the inflated price.
So therein lies the rub. Do you sell now at $100 to lock in profits or wait to possibly double current profits, risking another production run and losing any potential profit? I'm leaning towards the former....
