Well there's 2 versions that come with the new Icon/Lionsgate BD: 1.37:1 (academy ratio) and 1.66:1...
Judging by that Hammer article on aspect ratios, which was really informative, the 1.37:1 ratio is most probably the one intended by the makers of the film as the 1.66:1 cuts info from the top and bottom... Why would people want to watch this version? I'm not sure why it even included!
... Going to watch the BD in about an hour, can't wait!
