Zooming out further on your village may be a clue to...
we know that one of the un-announced features of the update was that you can zoom out a bit further on your village. this could likely be an improvement for those with smaller phone screens to be able to see an entire village, but I noticed something...
when fully zoomed out, there is more "space" towards the "6 o'clock" bottom of village area. this might mean that they are planning to increase the size of the village by 4 or 5 squares towards the lower left (water) and lower right sides.
this might make sense with the additional wall pieces, the speculation of a th11, and people complaining about village being too crammed as it is now.
