IIRC way back last year when the Predator series was first announced, Williamson said that it would be about an older Predator on his last great hunt, and the younger Predators trying to bring him down. Since the "last great hunt" plot seems to have gone unchanged, my guess is that the other Predators we've seen are the younger ones competing with Ahab. As to whether they're "Super Predators" or not, my thinking is that they'll leave it ambiguous, IE not really address it one way or another. Sebela has said that he thinks Predators was a dumb expansion of the series on Twitter, and the writers have stressed that they're only using Predator, Prometheus, and the first two Alien films for inspiration, so I think it's unlikely that Williamson or Sebela would write Super Predators into the series. Barring a Fox mandate, that is.
I've been wrong on many of the things I've speculated, though, so take it with a grain of salt.
