Wetlandernw from the Tor.com reread offered some insight into the cover DKS was working on, from her recollection of a conversation she had with Brandon at a signing.
In a conversation at a signing (14 September 2010) the subject of the cover art came up. My recording of the conversation got wiped out by a certain 9-year-old, so I can’t give the exact wording, but he said something like this. Mr. Sweet needed something to work with, to get started on the Memory of Light cover art, so Harriet went to Brandon and asked if he had any suggestions. He immediately thought of a particular event or scene which hadn’t yet been written, but of which he had a pretty good mental image. He wrote up a 3-4 page description of the scene for her; she liked it and passed it on to DKS. At the time of my conversation with him, he had seen (what I now realize was) the concept art, and he loved it. It was, in his opinion, the best in the series. With the awareness that Brandon has always liked the DKS art, it seemed like a pretty high recommendation. It also made me really want to see it—both the art itself, and the scene Brandon thought would be the perfect cover for the final book.
