My take on the new map:
1. Longer route
2. New building?
3. Changed cave entrance
4. Another cave opening...probably the dark glasses guy
5. One extra cave opening
6. Bigger ship maybe on an island?
7. New house?
8. Walled Mauville and it does look greener...green energy?
9. Looks like a team building activity, a parcour?
10. New cave opening?
11. Changed Jagged Pass and bigger cable lift building
12. New hidden route?
13. It looks like you can walk over Meteor Falls...probably not but it does look strange
14. New route?
15. Route changed in an ultimate rain forest
16. A hill, a new hill?
17. New top of Mt. Pyre
18. Dark Island, or distortion world, or fairy kingdom?
19. New something
20. Also new something
21. Bigger and brighter space center
22. Sea temple, do I smell a Manaphy?
23. Jacuzzi Sea Pass, dive spot
24. More houses at Ever Grande
25. Looks like giant dive spot + a small town?
26. The same but with museum esque buildings...ruins...Regigigas?
27. New cave and land?
28. Bermuda triangle
29. Faraway island?
Numberless red triangle: Sky Pillar
30. Probably nothing but who knows?
31. Battle Tower or Frontier, if it is a tower than maybe... Delta Emerald?
32. Cave route?
33. Extra house to the right of the berry master...the orange building or is it a rock formation?
That's it I guess!
