A classic play by Lego. They realized that DS had sold too fast with a limit of 5 and wouldn't make it to the end of 2014 like they had planned, so they leak that it will be around until 2016. The investors return their sets, probably in great condition (who takes better care of MISB sets than investors?), and refill Lego's warehouses. Now, with the topped up stock of DS sets and new limit of 2 per customer, they can at least offer them through the summer and fall, while devoting their production lines to the new Tumblr, rumored UCS Slave 1, and so on. As an added bonus, Lego gets to find out for sure who the dastardly resellers are (end users don't return sets just because they hear the production run has been extended). Well, played, Lego, well played.
