The report comes from KB from somewhere in Western Europe (anonymity is required since she had to sign the Non Disclosure Agreement!).
[Re.: Hobbiton] I was there and it's terrific! The hobbit holes are mostly ready and look as if you could move in next day and there are lots of nice details you probably will never see in a movie!
The Green Dragon pub and the mill are still under construction and we couldn't get near.
Whether the set will last after the shooting seems still a secret, nobody knows or want to tell. (Or let's put it this way: The guide said he wouldn't know, but he looked very pleased ...)
So, an interesting report - it sounds very much like Matamata's Hobbiton will be a permanent place, with complete sets remaining in place afterwards. Something else I heard today is that the bridge is apparently made out of steel, solid timber, and actual stone on the outside. I've been sent some photos by a different source, I might post a few of them a bit later, after I check with them.
