I have spoken to Arrow Films today, and they confirmed that the photograph of the box-set artwork which is currently shown on Amazon, is an initial mock-up. The box-set that is being released has appropriate, Second Series, artwork. The artwork on the box being released can be seen on the Arrow Films website, or, if you watch the video advertisement of the second series, on the Amazon site, it actually shows the artwork of the box, as it will apparently be sold. I am just a customer, so speak for nobody, but on this basis, I will happily purchase this Volume Three.
Also, I do own the complete Wallander Series One and Two, which I bought from Australia, and they do have some differences from these Arrow releases, at least in Series One. The Australian (SBS) Box 1 is Region 4 only, and has yellow subtitles. The other three appear to be region-free. Volume 2 (of Series One) of the Australian versions have quite a number of typos. Vols 3 & 4 seem perfectly OK. For myself, I had to decide whether I was willing to have two sets. On the basis that Vols 1 & 2 of the Australian versions have a few problems, I've decided I will get the complete collection from Arrow, in addition. All depends on how much you love your Wallander I guess!
