For me yes

Zelda is way more popular than Xenoblade, so no.

They aren't even the same genre. TLoZ is an action-adventure. Xenoblade is a JRPG.

Nope, they're aren't similar enough for either one to outshine the other.

not if it release few months later.

i doubt it will

They're too different to be compared directly but Zelda has a bigger fanbase so  there'll be more people that will remember it fondly

Xenoblade and Zelda will be different enough that they'll each stand on their own merits. I loved both Skyward Sword and Xenoblade. Each scratched a different gaming itch.

Well since I'm not a Zelda fan, Xenoblade will completely outshine Zelda U for me.

But let's just say I didn't know anything about these two franchises and I was just going by trailers. The Xenoblade X trailers and gameplay look far more interesting than what I've seen from zelda, imo.

Quality wise, if Xenoblade turns out to be as good as most people expect it to be... It'll be better than any Zelda game. But I don't like Zelda, so maybe that is blinding my outlook.
