Jurassic World Revisting Isla Nublar. But Also Someplace Else?

Jurassic Park Legacy posted this on facebook and it really got my gears turning.  "Empire teases that Jurassic World will indeed visit Isla Nublar...but head elsewhere after."

What on earth could this mean?  Are we going to visit Isla Sorna as well?  Could there be a possible third island?  Maybe we'll have another "inccident" like in The Lost World?  I'm really curious to find out, but I think I'm going to try really hard not to find out until the movie comes out.  Sounds like a possible plot-twist to me.
