I've read an excerpt from the e-book. Very intriguing. I hope they release a paper book. I'd definitely buy it.
Brin-Jonathan Butler (the author of this book) was also making a documentary about Rigondeaux called Split Decision: The Story of Guillermo Rigondeaux. It is completed but hasn't been released yet.
As long as they make it in Kindle form, that should be fine. It would have a very selective audience. Although if the get it on CreateSpace, it would cost them nothing to make paper copies because those are made on demand as ordered. Hopefully they will discover CreateSpace which is a subsidiary of Amazon and is distributed worldwide.
