Few problems though. Hybrids from the Ludia Inc. games are of their own property. Ankylodocus and Spinoraptor are presumed exceptions presumably because of the further support in merchandising in a "Toys come to life" toy line by Universal Pictures, meaning they already had a larger presence in their possession prior to their inclusion in this game, rather than confined inside stuff primary associated by another company. Frontier Developments are not associated with them and may have difficulty including them, especially since the way how the Secrets of Dr. Wu is made, I doubt they would expand it and the game's overall story and lore for more hybrids. In the Jurassic World saga, hybrids are introduced by very special means because they're meant to be very special from the regular dinosaurs, and just adding more in a simple "here's some more of that" DLCs or free updates would make those hybrids less special as opposed to the ones in-game already, introduced through fleshed out lore and story factors.
