Status of The Triangle Book I am interested in finding out about the current status of the planned book: The Triangle Book by John H. Conway and Steve Sigur. I understand that Steve Sigur died some time back. I got no reply from Prof. Conway; is there someone who knows the fate of this project. Is it abandoned or is it still under preparation? Here is some information about the planned book.
 A: The Triangle Book is on hold (Conway died this year) but there are people trying to revive it trust me.

A: Look at this link, they say they want to publish the book in 2014:

A: Conway's 2015 biography Genius At Play by S. Roberts, a 2016 text The Triangle by Richard Guy, and Conway himself in the first two minutes of his 2015 talk How Turning Triangles Inside Out Helps Us Understand Their Geometry say that The Triangle Book has not been written.
A: On a little googling , i find that the book is for sale

A: Has anyone got any news? This is still available on pre-order. 
When I contacted Book Depository at the end of last year, they apologised that its release date kept being pushed out, but all they could say was that it was still available for pre-order... i.e. no new information. 
Is there anyone with more inside or recent knowledge?
A: It might be assumed now that the book will almost surely never appear, both of the authors having passed away.
