I can wait for ADWD because there's loads of other good books to read in the meantime. HOWEVER while I waited patiently for 5 years for AFFC, I was somewhat dismayed to find that it was more of a side-dish than the promised feast. I had waited 5 years to find out what happened next to Tyrion, Jon and Dany. I didn't really care to the same extent what happened to Cersei, Brienne and the Ironborn
This was not a problem, as GRRM told us that he had 600 ms pages complete, with the rest in partial chapters, drafts and note form. We would only have to wait another year for the second half, and I was fine with that.
Now it sounds like he's rewriting the whole thing again - hence my increasing frustration.
Still, I don't complain, because 1. I know it will be worth waiting for, and 2. This is nothing next to the amount of time I've been waiting for Ricardo Pinto to finish his Stone Dance of the Chameleon trilogy. Now that has been a long wait between books...
