In these sequels, you all know that they have altered some of the region. But, can you think of anything else they have changed or what you think that they will change.

There's a couple of craters in Driftveil city and the Cold Storage. (Kyurem apparently fell to Earth on a meteor and made a crater at the Grand Chasm, connection maybe?)
There is a small black boat at Castelia Docks which in the first Black and White was owned by Team Plasma. (a hint at their return?)

Also, if you look closely through the ice, you can just about make out a couple of new islands off the shore of Undella Town.

A thread discussing New Areas already exists.
