Love this movie, great to see it coming to HD. One of the nicer looking steelbook, package designs I've seen. It's coming out in France which is region B although no word if it's region locked or not. Here are the specs and image taken from BR.com:
-2 disc release, DVD and Blu-ray
-Limited Edition SteelBook
-18-page illustrated booklet
-Exclusive interview with director Roman Polanski
-Fearless Vampire Killers Featurette
It's a Warner Bros release so it's likely it will eventually get a North America release.
