I voted no.
Predators are an alien species, and although they look like tall athletic buff men, I still never thought of the Predators as men/male. I see the Predator species as a very masculine yet genderless species with only one sex - hermaphroditic. They look more reptile than mammal and for some reason I always envisioned them being cycle-wise like seahorses but procreating somewhat like fish or frogs. Attraction and gender/sex-specific attributes just feel off and make the Predators too similar to humans.
The theory I've been playing around with goes like this: Predators live through cycles - the longest cycles are the asexual/infertile cycles, which last for several decade, which shortly segue into sporadic female/fertile or male/fertile cycles.
When a Predator is in its "female" cycle it dispatches roe-like eggs in spawning ponds. Predators in their "male" cycles produce milt instead of roe, and they will smell the scent of the roe in the spawning pools, which attracts them to deposit their milt in the clusters of roe in the nutrient-rich water. Both roe and milt are regurgitated.
Now, to make this more interesting I kind of pictured that the female cycle Predators will guard the spawning pools from hungry animals as well as from unworthy male cycle Predators. The "female" cycle Predators will challenge the "male" cycle Predators - either "herself" or by pitting two "male" cycle Predators against each other (maybe it depends on the clan). The winner gets to deposit "his" milt. Once the milt load has been dispatched, the "male" cycle Predator takes over the duty to guard the spawning pool, as the load hopefully will fertilize the eggs in the water.
Out of all those roe eggs only two or three develop and hatch into Predator spawn and the Clan, or parts of the Clan, will help guarding the offspring as well as keeping the nutrients in the water high until the infants are developed enough to feed themselves. In this concept Predator babies are more or less aquatic/amphibian, which is a trait the mature away from the older they get. Once they leave the water they will start being taught and trained to become hunters, warriors and whatnot.
In this theory the "dreadlocks" could actually be the leftover organs Predators have when they're in their most primitive form - organs meant to absorb and suck up the nutrients in the water of the spawning pool, or whatever body of water they were reproduced in. In other words - no need for nipples, boobs, penises and vaginas.
This would also explain the odd reproduction method of the Predalien hybrid seen in AVP:R.
Anyways. From a commercial point of view I can definitely see the allure in having female Predators with human female bodies heads down as that is the easiest and commercially safest way to appeal to the average gamer and people outside the Predator fandom. I doubt that Big Mama from Deadliest of Species is going to jive well with horny teenage boys and their expectations for boobs, legs, curves and tiny waists.
If they are going to introduce Predator females as different looking than the males, then at least make them flat-chested and skip the nipples.
