This looks like the single disc (+ uv digital copy) version to me. Doesn't it usually say "Triple Play" at the top? Maybe they'll update the image nearer the time. Meanwhile, I'll not pre-order until I'm sure which edition it is.
Yeah. They say BD+DVD+UV. Now, Ultra-Violet is apparently not the same as Digital Copy, so either they placed the UV inside the DVD or then they messed up. Play.com for example doesn't advertise a "DVD". they say only BD and Ultra-Violet copy. Across Europe the film was already released and everywhere the released version is only 1 disc (BD). So my guess is that Amazon screwed up and the 2 discs are just the BD and the Ultra-Violet and doesn't come with the DVD. (Which sucks 'cause I have no interest or use for a UV disc)
As far as I'm aware, the UV copy is a digital download, so this edition (like Play.com) is actually only a single Blu-ray disc. (At £17, the dearer price does suggest it to be Triple-Play, as the Blu-ray+UV Copy version is only £13.99 on a lot of sites at the moment). It is available as Triple play in the US, and as a Triple Play + CD Soundtrack in Europe; so why not here?
