Oh well, I'm not going to kid myself into thinking this might be a possibility since as many people already pointed out the species mentioned are as likely to be implemented as the Mosasaurus
Also, concept art for lures and similar looked to me like those on JPOG and somehow I cannot see Universal not imprinting their, well, print on them. And the Cretaceous Cruise.... man, if only it could exist within these shallow ponds...
Having said that, however, I have to say that the mechanics described, the lures and everything looks a hell great and I would be willing to get it asap. Something like this would really enliven the game.
