Rock in Rio will be hitting the United States in May of 2015. The event will take place in Las Vegas, NV and Bruce was hinting and rumored to be playing the Rock in Rio festival again next year. The Rock in Rio page for the United States tweeted out something very interesting when being asked if Bruce would show up: "and it's gonna be an honor have The Boss on Rock in Rio one more time. Remember: we are #brucebuds :)"
Sounds like they may have let the cat out of the bag that Springsteen will be playing at this festival next year. They did kind of backtrack however in a follow up tweet: "keep in mind that the official lineup will come out soon and we can't promise you that. 'Would be an honor' would be the appropriate sentence." So we have our first official rumor post 2014 tour!
