Looking at the back of the cover, it looks like you might be able to select the ratio you want. I much prefer this over being forced with the wrong ration. As it has cinema "widescreen" as well as "full frame" listed. That gives this release a bit more merit in my mind.
For those interested, this release finally got me to finish a post on cinema and TV screen ratios that I started when the first Avengers movie came out. It just managed to sit in my draft section for a long long time. On the plus side, I also got motivated to make up some better pictures for the post:D.
