What secrets lie in Thor's video game trailer and concept art?

Sega has released two pieces of concept art from the Thor video game, and we've got two more. Pair those with the game's trailer, and you've got a whole heap of potential Thor hints to swift through.

Here are two pieces of concept art: one showing the Surtur Forge, another depicting River Dock. Plus two stills we snapped from the Marvel booth at Comic Con. It's a little blurry, but there's one more location that we can't decipher just yet, what are your guesses?
