I recently watched the apple keynote presentation on Lion, iOS 5, and iCloud.  The presentation on iCloud is extremely impressive (it starts at 79:00.00) and part of it discusses the future of itunes (its one of the later things discussed. I highly recommend watching it; Apple has once again taken the bar, thrown it out, and created an entirely new standard for digital music.
