I ran this article through an online translator and it has some very interesting info:
Trent Reznor announced that its tour in 2013 will include several countries in Latin America
Mexico City.- Trent Reznor, leader of Nine Inch Nails announced that in 2013 the band will be on tour in Europe, the United States and Latin America.
The group's return to Mexico City will be the next April 18, the day on which they played in the Foro Sol.
The previous visit to the country of NIN was five years ago as part of the MOTOROKR festival.
Reznor indicated that in 2014 will go on sale a collection of hits by the band with some new songs. The announcement of their tour next year opens the expectations of its presence in Coachella 2013.
EDIT: According to Rob, this article is not accurate.
