If you read a bit of Spanish this interview of Mulero on their reconnaissance of The Dawn wall is quite amusing.

Well only 21 pitches really, the rest is easy. The climb is very repetitive, as most pitches has the same move over and over again, but that the two crux pitches are very hard. That Mulero wanted to do the Nose but there were too many people on it, so he tricked Hukkataival into trying Dawn Wall with him instead. That they had very little gear since it was supposed to be a bouldering trip. That they figure it will take them around 15 days on the redpoint attempt, since it took Ondra 8 days and Caldwell/Jorgeson 19 days.
