Coldplay México posted this a few hours ago... They don't say what they are talking about, but I asume it is about the tour dates (or maybe it's just about live 2012 and i'm falsely getting my hopes up
). They haven't confirmed nor denied anything though...
It says: "I'm waiting for information!! I got a mail and as soon as I can publish something, I will gladly share it with all of you. (they are official sources that work with EMI México.)
