Will there be a Jurassic Park 4 Toy Series?

Yes, as of now Hasbro doesn't plan to make any Jurassic Park 4 action figures; their main money-making products are Star Wars. But who knows? They may pick the license up again once they see that JP4 will take in money, or they may just leave the job for another company. But if Hasbro if fact doesn't pick the JP license when the film is coming out, and another company doesn't either, it may mean no JP toys.

I doubt that any toy company would even consider not picking the JP toy license, but you never know. I guess we'll just have to hope for the best...
