IMPORTANT: I took none of these screen shots. Indeed, I have no idea who did anymore. These were merely screen shots I saved because I liked them, and now I have no way of finding who I should credit.
Since the company Blizzard cracked down on sites like MMO-Champion to remove leaked Cataclysm images, it's much much harder to find any of the thousands of images that were out on the internet that crazy five days. However, before they were removed, I managed to grab several very detailed pictures and maps of Cataclysm. This is a compilation of these images for anyone who missed the leak, or, like me, can't find any of the surviving galleries.
