Not quite. Matt has stated in the past that he has allowed the Hunter's speculation be flat out wrong at times. @Takran laid out the fiction of Evolve pretty nicely, and Matt later clarified much of Takran's speculations.(I hope I'm not pulling an old man and getting this all wrong)
Either way, near Evolve's transfer into the hands of 2K, Matt dropped this fiction that suggested that monsters sort of make themselves out of their environment. In this case, a space station.
