The cover has been updated by Amazon for The Art of the Uncharted Trilogy. Instead of a generic black background, it looks like the book will now use what looks like a worn out leather design. You can preorder the upcoming art book with this page on the retailer’s site. Compare the new and old hardcover designs below this paragraph.

If you haven’t ready our previous piece, The Art of the Uncharted Trilogy features hundreds of concepts and designs from the first three games (Uncharted: Drake’s Fortune, Uncharted: Among Thieves and Uncharted: Drake’s Deception) that have not yet been shown to the public. Also included will be some commentary pieces from Naughty Dog.
The Art of the Uncharted Trilogy has a release date set for April 28, 2015. Also due to come out this year is the next videogame installment in the franchise. Uncharted 4: A Thief’s End is going to provide several significant changes, including adding more combat maneuvers and exploration abilities. Naughty Dog will also try to target 60 frames per second although it may not be a complete guarantee that the frame rate is going to be implemented into the final product. Uncharted 4: A Thief’s End is available for preorder on Amazon.com here.
