Yeah, there's definitely 4 WWA steels. Unless amazon get an exclusive too, looks like france are currently getting 3 of them. The 4th (bestbuy exclusive), with the cropped in shot of Adam's hooded head, hasn't popped up in france yet. Italy & Germany (i think) have it, plus other EU countries are also likely to get it.
This all proves that if they want to, like in this case to recoup/make some money on collectors, they can order up a bunch of steelbooks no problem.
Irritating actually, when 100s of better movies never had a single steelbook, or are not on Blu-ray at all!
