Uncharted Map Reveals Location of the Sequel?

Uncharted: Drake's Fortune is going to have a sequel, it was already said, and if you didn't know, you could tell by the ending.

A recent piece of art work sent out by Sony came complete with a document entitled ‘Lost and Found Treasures’. This document detailed the 10 greatest treasure hordes in the world and it got Games Radar thinking.

If Sony has gone to the trouble of researching these treasures and including the document within information about Uncharted, could one of these locations potentially be the setting for the next game?

See the three possible locations Games Radar thinks the next Uncharted could have in the link below.
