According to the co-creators, there is no Book 4 and never will be. A mini-series sequel to Avatar: The Last Airbender, currently titled Avatar: The Legend of Korra, is set to air sometime in November 2011.
At SanDiego Comic-Con 2008, Mike and Bryan showed a joke short made with fanart called "Book 4: Air." See the Related Link section below for a link.
