Bethesda's released nine high-definition screenshots pulled from the Fallout 4 trailer, and boy are they fun to stare at as you pretend you already have Fallout 4 and all the time in the world to play it.
That said, aside from sharper images, there isn't too much more here to glean that wasn't already covered in the trailer breakdown yesterday. However, the fact that Bethesda specifically calls them in-game screenshots does add weight to the notion that the pre-apocalyptic scenes weren't just constructed for narrative exposition, and that Fallout 4 may let us experience the non-nuked world for the first time (aside from a few virtual reality re-creations).
Still, this is apparently just the beginning - Bethesda says the world premiere of the game won't happen until its E3 stage show on June 14. I'm not really sure what "world premiere" means when you've already published a pretty detailed three-minute trailer and high-resolution screenshots, but more Fallout is tough to argue with, whatever you call it.
