An interesting development on SW's Facebook page:
The CD/Blu-Ray part is very intriguing because that seems to indicate surround sound, but I must say that I am more excited about the first part which says that this album "sees a return to the full partnership that made the first two albums such firm favourites with fans."
It concerned me that it just said CD/Blu Ray with high resolution audio and not CD/Blu Ray with 5.1 high resolution audio
