You think Game Freak will use Z-A as an opportunity to give Kalos some more original legendaries? XY were really lacking because they recycled the Legendary Birds and Mewtwo. They could create 3 or 4 new legendaries for Kalos. Hell, I'll even take Kalosian forms of old legendaries like SwSh did with the Legendary Birds and SV did with the Legendary Dogs and Swords of Justice.
