I guess I'm one of the lucky Europeans - got my KS GCW Zero way back in December to Finland. Though, I never got a tracking number nor a notification it was sent, so I was quite surprised when I got the notification from customs. So there could have be some improvement here (shipping something without any notification overseas is not wise!). I didn't give any feedback to the project / Justin for this, although I did think about dropping an email (maybe I should have, but I thought their email is already full with other requests, and I got my console, so...)
I believe it's probably due to few people running the (HW) project with Justin - and some of the updates at KS do give a reason why things haven't been moving so swiftly as the should have.
That doesn't give any backers their console, though. Still I hope everyone will get it eventually, and also hope thing will sort out for Justin (and the whole KS project) - I doubt he did this on purpose!
