All this news of King Kong/Godzilla crossover is really exciting and a dream come true for us fans. But on the other hand I really hope Legendary/WB/Universal don't get too carried away with building a kaiju universe and neglect making quality kaiju movies. This happened with Sony and Spiderman, I sure hope it doesn't happen with Kong and Godzilla.
As for crossing over with Jurassic World, I'm not against the idea. But on the other hand I don't see dinosaurs as kaiju or even monsters, I see them as animals. Godzilla and King Kong I think are more kaiju/monsters than they are animals. So I don't know how Jurassic World will fit into the kaiju universe. But hey if they can make it work somehow, why not?
I'm also sad for Pacific Rim 2, but I would love it if Del Toro would direct King Kong Vs Godzilla. He would be perfect for it and I'm sure for him it would be a dream come true.
