I've been searching around for wallpapers of the FO4 concept art, and the one's I've found are pretty damned awesome, however this one still eludes me: http://vignette4.wikia.nocookie.net/fallout/images/0/0a/FO4_Nora_Wasteland.png/revision/latest?cb=20151108073402

Has anyone come across a hi-res version of this image? The very nature of it would suggest one would exist.

I've not seen any but I'd keep an eye on Bethesda news page for any announcements
