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!
