How is a JWFK patch ridiculous?? If anything it's ridiculous to think that they would include Dinosaurs in a game from a movie that isn't even available to the public. Which is why it will come after June 22nd. A JWFK DLC makes total sense.
It's ridiculous because Universal has already spoiled those dinosaurs in way too many trailers for the film. If anything, it really matters very little whether they are in or not, but I think most would prefer they would be in from the start. As I said, it would be a big promotional push for the film if the game included them day 1.
