Well if that is true.
Remember the whole CM3 spcheel?
If the interpunct was a comma, then it went Phantasmal Species (Millennium Class Phantasmal Beast, Holy Beast). However the Magical Beast hierarchy is Magical -> Phantasmal -> Divine. So then if Holy Beast is separate, it's a classification of a 1000 year old Phantasmal Species; however, it is not a Magical Beast.
If the interpunct was a definition, saying the definition of a 1000 year Phantasmal Beast is a Holy Beast, it'd be even worse because that'd mean Holy Beasts are Phantasmal Beasts. And God Bulls are not.
Also seriously, the line in F/Z weapons page and the one in animation materials is exactly the same other just that they switched holy beast to divine beast. So I'm inclined to believe they're the same thing.
