Isla Sornas fate?

i think its still might be a preserve and it might still be heavily protected. but thats just my guess

Yeah, I wonder, although Masrani could quite possibly be using it as either a new park or a means if breeding/experimenting on the dinosaurs, gene splicing anyone? 

This is my conclusion:

1- Hammond said at the end of The Lost World (BY the movie canon) that the animals were going to be left to breed.

2- Since he said that, the island could possibly be protected by the government.

3- If it isn't protected, then the animals are just normally breeding.

4- I assume the island will return in the supposed sequels of Jurassic World, since they said they were planning to make a whole new trilogy.

5- Since I read the books, I'm just guessing they just continue to do what they do, with some of them escaping onto the mainland.

It's probably protected by the government. I wouldn't be surprised if Sorna makes a return in future movies. 

Well, now that I think about it I think Hammond did say the government was now protecting the site, so...

Current cannon, If I believe, Is that Sorna still exists.

It was never bombed after JP3, However, Control, and protection of it, Most likely fell to the US Government (As they were the last to do anything on the island) 

It could've been Sold to Patel when He bought out ingen...

Or, It could just... Be there, Not in use.

Another idea, Would be, That the Dinosaurs killed themselves out. Running out of food and such.

Hopefully, Colin adresses these holes in the cannon in the movie... If not... Well... -_-

EVAN123 - Now this is an interesting topic! Hmm, I'm of the opinion that Site-B is likely a biological preserve protected by the government and, as a result, off-limits to the public. That being said, perhaps Patel Corp has worked to reacquire Isla Sorna in order to utilize it as a "safari" location for high-paying guests. That could be extremely compelling! :)

Now that is something that could be really very interesting, SOMETHING REAL, an exclusive ride so to speak, that would be incredible, although this is Jurassic Park, I can't see it working out, haha!

EVAN123 - Hahaha! I know exactly what you mean, sweetie! Every idea for that franchise has thus far come to a less than pleasing fruition! I can't imagine what the insurrance policy for a safari like that would be like! :)

@Something Real, A safari would be AWESOME!

I don't care about the risks, I'm still a minor, I won't die, because its Jurassic Park!!! Haha, kidding aside, even with the risks I'd still do a safari like that.
