Looks like Cambridge is releasing a KJV Heritage Edition Bible and Prayer Book (1662) in three bindings: hardback, premium leather black, premium leather purple. Product Description (link)
I have the black leather. Very handsome publication. One complaint is that the Bible text is nearly impossible to read it's so small.
The size of 6.9 x 4.7 inches should be handy to carry about. If you go for readability, I guess owning separate editions of Cambridge BCP (1662) and Cambridge KJV Bible make more sense. But the heritage edition (both in one volume) will look nice on the shelf and in the pew. Is there some kind of essay or notes on the heritage aspect of both texts?
