The Austrian one has less content. It´s only the Director´s Cut on Blu-Ray/DVD. This one comes with additional Theatrical and Bonus DVD. Austrian one I have is slim and also has G2-size.
Here pictures of it:
Cover looks good, but only 4 pages and cheap paper. Foil is matte.
Because the Leonine Mediabook has 3 discs it will probably be a bit thicker: 1 thin plate + 1 thicker 2-disc-plate.
