Tor have revealed the cover art for Words of Radiance, the second novel in The Stormlight Archive (following on from 2010's The Way of Kings). Once again, Michael Whelan has created the artwork.
Words of Radiance is tentatively scheduled for release in January 2014. The reason for the lengthy delay between the two books was Sanderson's work on The Wheel of Time. With that firmly concluded, Sanderson hopes to deliver new Stormlight books every 18-24 months alongside shorter novels and novellas, with periodic breaks in the series (which will be ten volumes overall) to write other books, such as the two sequel Mistborn trilogies.
Sanderson has a wide-ranging update on the state of play of his various books and series here. His next book will be Firefight, the sequel to Steelheart, followed by Shadows of Self, the sequel to The Alloy of Law. These should both be fairly short books. He hopes to then write Book 3 of The Stormlight Archive for publication in 2015.
