Sony will be sponsoring her "massive" world tour later this year. They will be providing her technical equipment including arena speakers, projection screens, soundboards and are in the process of designing 2 Bluetooth microphones (including a headset that is almost invisible) that are expected to be frequence-free. They will also be selling a digital tour book on a disc: one side will be DVD while the other side is in Blu-ray format. It's unknown what will be included on the disc and if they will be selling an actual book as well or if it will just be the discs.
