@Noodles With France apparently getting the same Steelbook as the UK, it's looking increasingly likely that the forthcoming German one may also end up the same, notwithstanding the different artwork currently showing on Amazon and Media Markt. This title is, after all, distributed in all three countries by the same company, Studio Canal.
I think that the best prospect for a WEA Steelbook, with maybe something akin to your own concept artwork, is the proposed FAC release, since the distribution rights in the Czech republic have been licensed to a domestic distributor.
