This may have been addressed already, but I noticed many new areas under the ice.
Look where Victory Road was. It is still there, but there is another odd area beside it. There are also some other things on the area on the peninsula. There are also 2 new islands off the coast of Undella Town.
Of the areas that we can see (that probably have already been adressed), we can see a new area of the west side of the eastern mountains. (And just a minor observation -- there is now a plane shown in Mistralton, and there seems to be something that looks like one of that mountain settlement) There is also a big, new, blue building where the crane was in Driftveil City. The Cold storage is now gone and is replaced with a big hole in the ground. There is also another big hole in the ground in northern Driftveil. This means absolutely nothing, but the Liberty Garden and Unity Tower are now drown on the map along with boats in Castelia. Obviously, it also shows the newly finished construction on Route 4. One last interesting note is that there is no water surrounding the EntraLink, as there was in Black/White.
Please discuss anymore observation you have made, and anything that I said that was already discussed. Thank you!
I made a Picture, circling the areas I detailed in my post:
(This post was in the "May CoroCoro Scans" Topic, but I realized that this map goes with this post, and switched my post to this topic. Sorry!)
