Jurassic world

Quite possible. Also, did you see that teaser poster? It had a Raptor nest in the wheel well of Explorer 004 (the one Rexy pushed off the edge), and there was construction going on. 

Interesting I agree with Mr Happy

I'd say it's almost confirmed. For a couple reasons. We've seen the map, and the brochures. It Doesn't show any sort of raptor. I'm assuming that they didn't create any raptors because of how dangerous they are. But, we've seen raptor teasers. So I think its possible that they break into the park and, do what raptors do best. cause trouble. 

Finally! Someone who thinks the same! I totally agree, especially when I saw the poster! I even said in my summary of Jurassic World here that the raptors might be out, and maybe even other dinos!

I think that whatever raptors alive after the first incident are now being studied by Chris Pratts character and are definitely not on show, and I do agree that the perimeter fence is keeping things out rather than in which is a rather unusual and interesting way of going about things!

The wall to the north of the visitor area is almost certainly heaviy involved with whatever is going on.
