This is what I expect. Give or take 20 hours of main story. I figure if you want to completely rush through you'll probably be able to finish in under 90 hours.

I'm curious as to how quickly one could 'rush' through Xenoblade... I kind of want to try it.

I'm not saying that I'll be "rushing" through it, but I much prefer it when a game has a stronger back end. I want to have a reason to stay in the world after I beat the main game.

I'm ready!

More info (shout outs to a member on gaf)

-Xenoblade was traditional RPG, whereas XenobladeX is an open world RPG. Xenoblade was linear despite having big world. XenobladeX you will get quests from different places and have more freedom.
-Xenoblade had 1 vocal song at the end, but XenobladeX has many vocal song. (Many for RPG)
-Mira is 400^2m which is 5 times Xenoblade. So there is Dolls which can fly. Also you can check your location via gamepad
-Battle system is based on Xenoblade, but it's faster paced and more action packed.
-4 player party, you control 1 and AI controls the rest.
-number of unique monsters and equipments have increased from Xenoblade.

Wow, I was later to the party on this than I thought. Had a duplacate thread, lol.

Good God.

This world no longer has a need for gods.

Guys can we get a comparison to this →→→→→→→→→→→ Mira is 400km

Im looking up other gaming worlds, i want to compare :0

Well I imagine the campaign length will vary so very drastically indeed. I mean, let's have a look at the first area that we saw in the game at E3. You had two options; take the high road and go to the colony (probably takes about 5 minutes), or take the surface road and find your own way there (and given we saw very little of this indeed, could take well over an hour).

So saying the campaign will be 60 hours long doesn't make a whole lot of sense to me, sure you might be able to "rush through" in 40 hours and I'm sure this option will be there for reviewers to exploit. Having said that, that length could easily double depending on what route you take (and how much you use the mechs, ofcourse), and then double or even treble again for sidequests/monster hunting/exploration.

All I'm hearing from this is good news, really. It's frustrating I can't read Japanese all too well because I'd love to know more!

How wrong you are :)
