Pardon the double post, but I had a thought:
While there's new Jurassic stuff for FFN, you think they won't discount them eventually since it's an IP that's always present at the park? My gut says they most likely won't, since the Yoshi stuff from last FFN stayed around.
I get the feeling the same will apply for Jurassic, so I think if I decide to get something, I might as well do it.
