If it's something familiar to most users, like iTunes, then Apple may feel a press conference would be a waste of time. Besides it gives people time to leak information. Have you noticed how flat Apple's keynotes have been, in terms of audience response lately?
As it's iTunes related i tend to agree with Solipsism and think it'll be a web-based iTunes model.
It's dominating the homepage of most of the Apple sites worldwide so it must be fairly big, as that's a lot of advertising space to give up for something trivial.
