Also, yeah, you're right, there was some differences between the boxes themselves from region to region. For instance,
the annonced Heavensward CE (on stream) had a box opening on the side with two panels being deployed, as well as a steelcase for the bluray. In Europe, no steelcase, just a cheap cardboard CD sleeve, and a overall box that opens by taking off the top part. Even the artwork on the box itself was different.
So, yeah... I wasn't particularly impressed by Heavensward's collector edition, but it was "okay-ish" for its price. Which is why the Stormblood one, priced 70 bucks more is a big no for me, unless something drastically changed from the Heavensward's one (but it doesn't appear to be the case).
