This is really late, but Survivor 6 should now be shooting in the Amazon. Survivor Maps has the details on the site, including photos, maps and other information (they have had great detail on each of the Survivor sites, before shooting even begins).
"The Production Camp will be located at the posh Ariau Towers Resort reserved October 22 through December 22. "
"Sources say the Tribal Camps will be located on the Rio Negro's Praia Grande (Great Beach). Rumors say Tribal Council will be deep in the Amazonia rain forest on the Rio Acajatuba near Acajatube Village."
