It sounds like Jurassic Park 4 is returning to Isla Nublar. The most obvious plot (to me) is that a big game hunter will be organizing 'unique' hunting expedition which of course go horribly, horribly, horribly wrong. He'll need something to attract lovable, yet hopelessly naive billionaires, so on his office wall is a Hunting trophy!

Jeff Goldblum will invite himself along and later, shaking his head and looking at the first body will say something like 'Oh look, another demonstration of survival of the fittest'. That's the film I want! :)
