I disagree I'm afraid.
There's really no need to emphasize Wolverine as much as they have. While it's a known fact that he's the most popular character in the films, at this stage no one's buying the steelbook for his appearance alone. The cover would have been better with the original image of them standing in a row, not this Photoshopped version with Wolverine now lit up like a Christmas tree. He was still front and center like he is on every X-Men cover it seems.
There's just no consistency with the front artwork on the X-Men releases. The first steelbook had the theatrical poster, the second used the US DVD art and now we have some amalgamation of different DVD/Blu-ray designs. First Class used teaser art, Origins used your standard 'Wolverine is the man' design and then back to teaser art for The Wolverine.
No doubt by the time DOFP comes out, it'll basically look like Wolverine VII. Hugh Jackman is after all, the only actor whose name appears before the title in the trailer (just look at the credits).
