Ay up! Perhaps the UK might not be getting so "screwed up" after all. I've just seen a listing for a copy of the 2 disc DVD of Requiem on Ebay. Although it's a Region 3 copy, the cover is almost exactly the same as the UK version. You can see one or two lines on the cover that show the cover was scanned off a sealed copy of the DVD as well, so it's a real one. It even has a picture of the back cover as well, which, I guess, will be pretty much the same for the UK release too, and it says (clearly enough to see) "Includes 7 additional minutes of blood soaked action too shocking for theatres". It said the same on an R2 single disc preorder case of the film I saw in Woolworths as well, so, whether you get the single disc version, or the 2 disc one in the UK, you have nothing to lose (unless you want the special features as well lol ). Unfortunately, I can't find a picture of the R2 back cover, so I can't show proof of that.
Here are the pictures of the 2 disc version's cover:
