I'd like to see the next Zelda to be half-land, half-water. That would be cool. But I don't think that the boat will be back. I wasn't too clear, but wasn't the boat really the King of Hyrule in a different form? If he was, then he definetly won't be in WW2, cuz he stayed behind, remember? It would be cool if your mode of transportation in WW2 could go on land and water, like Dimitri the Dodongo in the two Oracle games.
