Doesn't matter really. It's still an open world rpg, and a very grey looking one too. For the entire last gen we've had more than enough of those. Nearly every other rpg looked that way (skyrim, witcher, dragons dogma...). To me, Xenoblade was always the exception to that ongoing trend. It stood out, even the most barren areas had something that felt out of this world thanks to it's color scheme. If it stays the way it is, I don't think it will make as much an impression as it's predecessor did, because besides some variety in terrain, it would look just like any other rpg/game of that era, just with added mechs/dolls.
Ofc we haven't seen anything yet, but judging by what we saw so far, I don't think it's going to drastically shift in other zones.
But I'll try to stay optimistic, after all it sold me a wiiu sooner as I expected (as soon as monster hunter is released)
