Speaking quietly from the background, it appears that most of the speculative posts are almost desperate for facts and certainty regarding the fate of 3 hard climbers. There is no certainty in life or climbing.
One of the reasons that James, Hall, Cooke and the rest of us climb is an attraction to the unknown, the lack of certainty. Not everyone needs to buy someone else's guide book. Some of us are born with our own and it is completely blank. We just fill it in as we go.
Having been on an epic or two myself, I sense the loss. But 3 "hardmen" don't start a climb of this magnitude without a firm grasp of the objective hazard involved. James had a problem and hunkered down while Hall and Cooke headed for help up and over or across the southeast aretes to descend to Timberline. After a few days James realized he could wait for help that may never come or go for it. He made his best move and stopped when he could go no further. I would have done the same.
Hall and Cooke also knew their chances and their story has yet to be read.
Certainty means little to those who understand "the higher you get, the higher you get." So James, Hall, and Cooke will climb on. That's who they are.
