So the box art work is supposed to be the Wanderer? It appears like that from the thing on his forehead.
How I see it, they just made this piece of art, then it later begun to evolve from there. I see the wonderer and death, metafore "what to come of him".
Yeah that would be cool, and then in the form of a special event, one that occurs rarely and drops some use full stuff..
The body is destroyed in D2 cinematic when Diablo "true form" is out. But that doesnt say that the old warriors body could be in an alternativ dimension or a small part of diablo? I mean, its a fantasy world, anything could happend as long as it is cool!
