I really feel like this one is about to crash, too... easily lost as it is amidst the plethora of more desirable, more unique, more exciting exclusives already jumping on the new retirement bandwagon.
Is it truly as poor of a seller as it seems? Why? Perhaps because anyone interested in it to begin with already has two or six other X-wings of some sort, all much cheaper and paid for? Stickers, huh? PPP, you say? There was already a UCS X-wing? What is the real draw here, exactly?
Assuming some sort of truth in that assumption, my big question is whether the lack of interest will carry over into the EOL years to come, making this a poor to average performer... or if it will translate into a massive supply/demand imbalance due to the corresponding rarity of the set on the secondary market.
A potential UCS TIE Fighter in the near future complicates predictions even more. It should raise demand for this set in its waning months (unless that time is now) and/or post EOL, . It would also demand shelf space, which conventional logic would dictate comes from the Ewoks. It might make more sense to try and sell this ship alongside a TIE... stretching its lifespan considerably. Or there might be no such idea at all. I have a hunch the Ewok Village is around a while, though, especially if 10188 finally bites the bullet soon.
Episode VII and a new X-wing design? How quickly will Lego have to jump on that situation and what does it mean for this set?
Honestly the way things are going now, they could have stopped producing it already and we might not know for a long time. It wouldn't surprise me if there are still a comparable number of R2's in B&M stores out there at this moment. With much more available capital I would prioritize this set pretty highly these days, knowing it could be a very high risk / high return venture.
