BTW it's going to be released first in US, 11 November (UK is 2nd of December). It's a bit more expensive on amazon.com for the same set (but you can get the 1 disc only version).
The only big difference is the 3D version that will not be available for the time being in US (exclusive deal with a TV manufacturer). In UK it will be available as the other versions the 2nd of December
And the US set isn't just "a bit" more expensive - it's about double the price without the bonus discs. So yes, US customers - if you can wait a few weeks longer buy this UK set and you'll be much better off!
All Warner Brothers (and Universal) blu-rays released so far have been region-free, even if it doesn't say so on the packaging.
On all of the region-free blu-rays I own any SD menus/extras/special features etc. are encoded in 480i/480p which means it will work on any blu-ray player around the world. It is 576i/576p that some blu-ray players/TVs in former NTSC countries have trouble with, but Warner Brothers/Universal don't use that encoding.
You will save a lot of money ordering from Amazon UK (or other UK websites) as a LOT of blu-rays are cheaper over here for some strange reason.
Thank you so much! I was very concerned. Another question, if you don't mind. Does the pre-order price stay the same until it's released? Also, when it's released do they jack up the price? Thanks again.
If the price increases after you pre-order you will pay the price quoted on the day you ordered. However, if it decreases you pay the lower price. Amazon may change the price after the release date, but that is for them to decide.
Also, outside the EU the VAT (sales tax) of 20% will be deducted from the price. Prices in the UK are shown with the VAT included.
Both versions will be 16:9 (or 1.77:1) disc, but the films will be in 2.40:1 ratio so you still have black bars at the top and bottom. If they were cropped to 1.77:1 then you would have parts of the film missing from the left and right.
