I was spoiled this in one of the streams last night regarding the locations and structure of the game, but I don't know if it's legit since I bailed out when I saw it. Warning, spoiler of the game structure and location list:
1st act in Lucis, completely open world: Leide, Duscae & Cleigne
Altissia has its own map
2nd act in Terraverde, closed big areas connected by train: Accordo, Solheim, Niflheim, Tenebrae
3rd act in "the world after" or something like that, very linear
Ending in Insomnia.
Answering to your question without spoiling everything else, it seems likethere are big enviroments after Altissia but they are not connected, you need to take the train to travel within these regions. The game areas become smaller as you progress through the story.
Sounds absolutely fine to me, truth be told.
