Read Will's initial response to your OP. Track records are everything: Will announced he would make a great presentation at FAIR. He did. He said he would post videos of that presentation on the Internet. He did. He has since announced that he will publish his findings in a more complete fashion both in print and on a blog. He will.
Brent? Well, some seven years ago, he announced on ZLMB that he would be publishing his critical text of the KEP--of which he has had great photos for 25 years--on or by the Prophet's 200th birthday-December 23, 2005 for the history impaired--and it's now August 12, 2010. I'm not aware of critical text of the KEP published by Mr. Metcalfe. Are you? Nuff said.
