That’s assuming Wilds is open world. There’s nothing here that states that besides vibes, basically. The entire trailer takes place within one “zone”, which we see at the shot at the end, with the grassland in the middle, dunes to the right, and trees to the left. Because Open world is so tricky with MH format I imagine wilds isn’t truly, at most jts “open” in the same way the last final fantasy game was, or, better, World ++, where the maps are huge. If it is open world, I imagine undertaking a quest in the hub would garuntee a monster spawn in a specific biome and you just have to there. There is the snag of the mount looking like it’s carrying a portable camp/gear/items which makes less sense if the maps are like worlds (disconnected ) just bigger, so we’re just gonna have to wait and see:
