Which will be bigger: Xenoblade X or Zelda Wii U?

I just got to thinking, Xenoblade X's world is apparently huge, based on what's been said and the fact that it's out in Japan, but Zelda Wii U is also set to be an open world game in a huge world. Which game do you think will end up being bigger?

I honestly don't think Zelda can beat Xenoblade's world. It might be the biggest world in a Zelda game, but Xenoblade X has an insanely big world from the looks of it. Now I'll probably end up enjoying exploring Zelda's world more, because I enjoy Zelda more than the original Xenoblade, but it's not going to be as big.

Hopefully both games will be as big a world as the other. I think of both games differently, one with an epic story & scope over time. The world growing in it's time; that world being Termina. Xenoblade Chronicles X's world turns from humans being Earth to having to leave to go to another world that's bigger then Earth is; I mean.. If you look at that world even the creatures are as big as the planet; so of course it's going to seem massive by Termina's (or even Earth's) comparison is what I think.  

Still I'd vote for both being huge. Just in varying degrees. :3

I think Xenoblade Chronicle X's world will be bigger then Zelda U's. Still I'd like if both games were massive in world scale though.

I think Xenoblade since the game takes 300 hours if you go for everything and Zelda's world looks more empty from what we have seen.

Oops sorry the second I saw the title I thought you meant which will be bigger as in more popular and immediately voted Zelda. Excuse my obvious Zelda bias.

From what I remember, Xenoblade X has an extremely massive world. If that's true, I honestly think Zelda's won't be bigger than Xenoblade's. They will likely both be large but Xenoblade might crush Zelda Wii U when size of the worlds are compared. Maybe Zelda will be bigger, it is possible. I wouldn't mind if it turns out smaller.
