Her new single recently leaked and she's rumored to be performing at halftime during this year's Super Bowl – so there's no doubt that the Madonna machine is gearing up for a big 2012. She stayed off the road for most of the 1990s, but in 2001 she came back strong with the Drowned World Tour. She followed it up with even bigger tours in 2004 and 2008/09. While it's impossible to say for sure, if she does perform at halftime, expect her to put the tour onsale the following morning. Tom Petty and Bruce Springsteen saw big success with the same trick.
Likelihood: 90 percent. In 2007, Live Nation made a $120 million deal with Madonna. They aren't paying for her to sit home and not tour, especially when supporting a new album. A fake itinerary hit the web a few weeks ago showing Madonna at stadiums in America, but expect to see her at arenas. Also, expect to pay a small fortune for tickets.
