What I mean is that the secondary build may be more significant than usual. If we look at the builds in the three Winter Village sets with piece counts over 1000
Cottage - 1490 pieces - Large, elaborate cottage (IMO out of scale with the rest of the winter village), a vehicle, a small shed
Market - 1261 pieces - Moderately sized carousel, and three minor stands
Fire Station - 1166 pieces - Large building, vehicle, pond
In the descriptions, I've omitted the tiny side builds - benches, igloo, tree, etc. I'm assuming that Lego is going to do something remarkable for the 10th anniversary set (this may be an incorrect assumption). With 1400+ pieces, I'm guessing we see one of two things:
1) A very elaborate Gingerbread House, which would hopefully still fit in with the rest of the winter village, along with 1-2 minor builds
2) A Gingerbread House more in keeping with the caliber of the toy shop, bakery and post office, along with a secondary build more significant than we have seen before - perhaps even another building that would be nearly the same size
We haven't seen a winter village set this big in over five years. We saw last year that Lego can do quite a bit with 1100 pieces, so unless they go overboard on the gingerbread house, I'm betting we get something like option #2, maybe with 1.5 - 2 full scale buildings - along the lines of Assembly Square.
