Here's my opinion on this new method:
First of all, this regurgitation method makes MUCH more sense, than the egg-morphing idea (which is also neat, but I don't think works for the Alien cycle).
To me, this regurgitation is just an alternative "face-hugger" and an interesting survival method. When the Queen is young and not ready to reproduce the masses of eggs through an egg-sac (and assuming there are no other Alien warriors around, at the time), the Queen will run around and quickly plant hosts with embryos that are probably in much more advanced stages, than face-hugger embryos, thus the embryos that are regurgitated will burst faster. The face-huggers have a slower process of "impregnating". but there will MORE of the face-huggers, when the eggs are layed, of course.
So, once the Queen has enough warriors to help construct a hive, she goes into hiding within the hive and matures, thus she becomes full-grown, produces an egg-sac and starts to produce the hundreds to thousands of eggs, which do the process at a slightly slower pace, but at a much grander scale.
Now, when the Queen is running around "regurgitating" the embryos, I think the process of the embryo being created inside of her will be faster than a facehugger, but the time in between the creation of the embryos will probably not be in a matter of minutes, but certainly not as long as human pregnancy, for example.
Ok, so again, the Queen quickly creates enough Alien warriors to protect her/create a hive for her to hide in and grow an egg sac. This is a survival tactic that makes sense. This method is far more quicker than a human being turned into an Alien egg, which in my opinion, conflicts the idea of a Queen anyway. The Queen is the ONLY one that should produce the eggs.
Now, this molting into a Queen idea...well, if there is no Queen, when there are Alien drones running around, you could argue that's when egg-morphing could occur, but let's not bring that into play for the cycle...to me, yes, Queens should be born through a chest-burster, (as we have seen in previous movies). In ALIENS, I assumed the Queen was born through a chestburster, which probably bursted out of Newt's father (sure, the chances are low, but there's a chance). I'm hoping that the PredAlien is just a Queen that is "maturing" (molting). I don't like the idea of an Alien warrior, suddenly becoming a Queen, just because there is no Queen present.
Hell, how would this apply to ants and bees? Is there ALWAYS a qeen bee or queen ant born in a hive?
I don't support the egg-morphing method. Remember that the idea was brought up, before Cameron thought of introducing a Queen to the cycle. So, the egg-morphing cycle should be thrown out the window. The method does not fit with the "Alien" characterstic, anyway. Maybe it would work for another type of creature, but certainly not the xenomorphs.
I think Queens should be born as chestbursters, just like the Alien drones/warriors. For an Alien warrior to change sex and start to develop into a Queen, because it can and wants to, does not make sense. Now, if this is something only a PredAlien could do, since it's a "freak", then MAYBE it would be ok. But a normal Alien drone/warrior....um, no.
