My fear is that Lebbon doesn't get the predators or that he consciously departs too far from the earlier material
To me, the defining characteristics of the predators are
Technologically advanced but culturally primitive
Savage, nomadic hunters
Enshrine a brutal code of honour
...but hypocrisy, cowardice, jealousy, ambition, and "dishonourable" conduct is rather endemic in predator society as hunters are often able to get away with a lot of bloodthirsty butchery and backstabbing
