The theory of a regular adult molting into a queen is not entirely out of the question. I consider the first two movies as canon, the first one, the limitations of a regular drone alien, and the second one, the limitations of a queen. But if we only viewed the first one as canon, the whole queen concept would be way out of line. J. Cameron saw a gap there and filled it. Same thing with the molting into a queen. Its about time for the aliens to experience something new, and as for whether I like it or not, I'll form my opinion after I see the movie.
