Lets clarify some things.
The sample I had a hands on look at might not be the version that will be released to the market in HK.
The front of this sample has just the embossed arc reactor image, with an embossed frame. The back is an image of Tony Stark. It should be the same as the UK version, which is supposed to have an embossed arc reactor.
The sample had a slip, like Taiwan steelbooks. The datasheet info on the back looks to be for the HK market and has the IVL name on it, which is the distributor in HK for this release. The final version may not have a slip.
Because the promotional material shows the back image (Stark) as the front, either this sample is not the HK version, or they are showing the back as the front purely for marketing purposes.
