As for contestants, I'd say this won't be an All-Stars (but I have a huge list of who I want to return)
This season will definitely visit a new country. Slovakia, Slovenia, Laos, Nepal, Latvia, Central America, and maybe to an extent some Caribbean Islands (Bahamas, D.R., Barbados, etc.) are the most likely candidates. I think we'll see a revisit to China or India, but hopefully not both. I also think this season will not visit Indonesia (unless WRP just wants to make us mad
). Australia and the Philippines are also a possibility. I think Africa might be skipped over again, but if they do go there somewhere besides the typical southern African safaris would be nice (how about Gambia, Ethiopia, or Morocco?).
