Yes, it's time for tour rumors again. Two years after the Reunion Tour ended in New York City, it's heating up again. Six days in September are being held at the First Union Center in Philadelphia for an as yet unknown artist, and employees at the venue speculate that it could be Springsteen. Other tour rumors suggest that the tour could kick off in Boston, maybe as early as August, just as venues in the North West are said to be under consideration for shows around September. While a tour seems certain, these are only rumors and speculation so don't hold your breath about anything just yet.
