July 2006: Obviously, May passed without an update from GRRM. On June 30, GRRM wrote of ADWD on his blog, "I still hope to deliver it this fall, or by the end of the year at the latest." He did not detail his progress on the book.
December 2006: With the new year fast approaching, GRRM admitted on December 6, that ADWD would not be finished in 2006. He decided against giving further estimates on the book's completion, as missed deadlines have only added to his--and fans'--frustration.
January 19, 2007: Alongside the announcement of HBO's adaptation of A Song of Ice and Fire, Variety reported: GRRM "has nearly finished the fifth installment, but won't complete the seven-book cycle until 2011."
February 15, 2007: On his Official Website, GRRM reiterated that he will not provide ADWD progress reports: "The truth is, these updates do make me feel like a twelve-year old trying to explain to teacher why he isn't turning in his essay, and knowing she isn't going to buy the 'dog ate my homework' ruse any more than you guys do."
November 26, 2007: In an interview with Entertainment Weekly, GRRM insisted, "I'm working on it as hard as I can. Writing it tough sometimes, and it doesn't always go as fast as you want it to. [Sighs] One thing I've learned is to stop trying to predict when it's going to be done."
February 8, 2008: GRRM wrote on his Official Website, "If I can just finish DANCE this spring, there's even a chance the book itself might be on sale in Calgary." Calgary refers to the World Fantasy Convention, which takes place October 30-November 2.
February 19, 2009: In a response to his skeptics on Not a Blog, GRRM admitted that he's been too optimistic on his projected release dates. He added that he hopes to have ADWD finished by June and released as early as September.
June 23, 2009: On Not a Blog, GRRM again broke his self-embargo on ADWD updates and said he sees "a glimmering that might just be a light at the end of the tunnel." Also the first explicit reference to GRRM's "Meereenese knot."
August 1, 2009: GRRM's editor Anne Groell said she expected to have ADWD in her hands by November and suggested a February/March 2010 release date.
October 9, 2009: Via Not a Blog, GRRM said ADWD had crossed 1100 manuscript pages with "considerably more in partials, fragments, and roughs."
February 9, 2010: At 1205 pages, ADWD had surpassed A Clash of Kings to become the second longest novel behind A Storm of Swords. (via Not a Blog)
February 15, 2010: ADWD is "Not Done Yet," but now 1261 pages and counting. (via Not a Blog)
June 16, 2010: GRRM is working on ADWD's epilogue, but still has other chapters to finish/rewrite. (via Not a Blog)
March 3, 2011: ADWD isn't done yet, but it's close enough for GRRM, his publishers, and his editors to announce a release date: July 12, 2011. Both the United States and the UK will see it released on the same day. (via GRRM)
