I get the info from tap's blogpost actually.

p.s. The page number reduction is probably because, each volume of English SAO is 5-1/2″ x 8-1/4″ large which is much larger than Japanese original release, plus English can be printed in smaller font size, so there could be more word on same page and reducing amount of pages needed to print the book.
