Yeah, but the additional features on the cut footage, audio commentaries ("The final Chapter" has got 2(!!!) tracks!) and interviews WOULD make these also into must buys for the EU fans which aren't crazy over importing all the cool stuff on R1s
The "Deluxe Edition" clearly seems to be what the "Ultimate Edition" box set (R1) only hinted at...so it'll be intersting to see in any case how the upcoming DE of "The new Blood" will look like....
