Great news Ron.
Sony's press release specifically states 2 different versions will be on the disc as well -- the "extended cut" via seamless branching. :)
I'd personally wait for the UK disc if you have the option of playing it. Warner's source used has faded colors and I'm wagering a properly restored scan is going to best this disc. It's very good -- but it could be better.
The other element is the sound -- I did not hear much, if any...
I have the disc -- it is region free, but it is 1080i50, meaning it's only going to work on a Blu-Ray player that can also output PAL. On my Oppo it works perfectly, but on my Sony it just plays with a black screen. I would see if your Blu-Ray player can play PAL content before importing.
It's...
