I didn't think it was very much in the Predator 'ethos' to have honour-based combat where one side is wearing the equivalent of several inches of steel plated armour, that really doesn't sound like the way I imagined them.
Edit: Though, in honesty, I never quite understood the Predators 'Thermonuclear Deathsplosion' either, why wipe out a large area simply because the hunt ended badly? That sort of goes against the image of them that was put forward as well, destroying the evidence of their existence, that I can understand, but that just seems a little over the top.
