This may be silly Beer speculation, but... what if Jurassic World 3 ends in a way where it’s now called Jurassic Park again? Blending the dinosaurs with humans and changing the name? Idk that may sound really stupid, but since this is an Universal owned IP, they may have the synergy knowing Jurassic World and Park are ultimately somewhat the same place. Thus the inclusion of Chris Pratt and Blue isn’t so random. Could help with their little upgrade to the land here.
OR, it just doesn’t matter. More likely answer here but I figured I’d throw that out there
