There was talk of some extra atheist publicity going ahead towards the end of 2009 after the original campaign finished and remaining donations to the campaign were to be spent on it - I thought it would be more ads of some sort - but I guess this book is it? I don't hear anything of anything else happenning. Anyway, the book sounds fun. I guess it makes for an interesting new direction for the campaign!
Just to answer my own post... I have found out that apparently it is not the case. The rest of the money will still go towards some more ads. The publishers have funded this book. I believe the profits are going to an aids charity this time
