The final eight shows of the tour are supposed to be in South America. Off the top of my head there are two in Brazil and the tickets should be on sale soon. I'll look into the details for you and post them. I plan on seeing her in Canada (Vancouver, BC to be more specific).
Also if you guys don't have your tickets for Boston yet, they've added a second show to go on sale soon. Don't miss out! I think the sale starts on the 25th or something like that.
