I figured since people have been enjoying the stunning views of the new world, I might as well snap some screenshots as I go.
Here is your only warning. This thread will be full of pictures of the new zones, sights, and interesting things. If you don't want that spoiled, stop reading now.
Explorers are going to have a field year with the new zones. The old world is full of things to see, even the things that were in the game from the beginning you can see in new detail, from new vantage points, with all the new polish the game has to offer.
So, let the photos commence!
(Note: all screenshots are full-size, so right-click them and view image, or whatever is appropriate for your computer/browser if you want to see them even bigger. Shots are taken at 1920x1080 resolution with graphics settings on Ultra.)
