I thought I'd share something with you.

One of my friends told me today of a mythology that may have inspired the makers of these legendaries. It is set in a world divided in three parts, one above the other. The master of the upper part was a bird. The ruler of the middle part was a deer. The one to rule the bottom part was... A gryphon.

Therefore, if they really got inspired by this legend as my friend thinks... We may be seeing a gryphon legendary as the Z pokemon. Gods this would be so awesome if they make it look good. I'm hoping so much that my friend was clever with his thoughts here XD.
