On one hand this could have been the perfect opportunity for a South American themed section, but being this is pretty much a sci-fi version of Beastly Kingdom I'm all for it.
Also interesting considering say TDR decides to build a third park based on the sky (DisneyLAND, DisneySEA, DisneySKY, see what I did here?), it would be a perfect fit over there too. It's too obvious for someone on the inside not to be thinking this.
