After seeing that Sandship dungeon in Skyward Sword again, I'm really disappointed at the BotW Divine Beasts or the BotW dungeons in general. The Sandship had a well design, cool mechanics, good puzzles, a lot of enemies, past & present and so on whilst the Divine Beast did not even have their own individual - nature adapting - design, almost no enemies, no dungeon keys, etc...
Lola's return in the cover story looks like a real ass pull to get her back in the story and to reunite her with Chiffon. That may be also a pretext for her to appear during Elbaf arc, for Loki to be introduced in the main story and for her mother to return in Elbaf.
I would have loved to see a Vegapunk arc with us seeing the Marine Scientific division HQ and labs and the various inventions and projects they work on, including the new Pacifistas, Vegapunk's weapons and others. But it seems that Vegapunk will instead appear during Wano or Elbaf arc.
I imagine that we'll see marines coming to Wano sooner or later, they just can't be completely absent of the arc events. I imagine that at least Smoker, Tashigi, Vegapunk, Sentomaru, Kizaru or Fujitora may come. Fuji's df would be ideal to allow them to enter Wano since he can make levitate the marine ships.
