Those SA dates are all old from Last.fm. They haven't been updated in weeks on there though, so the Sao Paulo venue, for instance, is different. The Lima date was finally officially confirmed by the promoter yesterday, but no confirmed venue.
Also, the rumoured dates currently have two cities on the same day, so at least one of those is incorrect.
This is often the case with big SA tours though. Little bits of information leak out all the time and everything changes once the official confirmation comes out.
All but the Mansfield date on the NA run were officially announced last night. Pre-sales starts Thursday using a code from here
. General on-sale on Friday.
