Music just doesn't leak early like it used to. Back in the old days (meaning...say...5 years ago) albums ALWAYS leaked at least 2 weeks ahead of time...often more like 3 or 4. But nowadays that just doesn't happen. Maybe there's just been a loss of interest in the music business (as we've seen with record sales), I'm really not sure.
Now, of course, it certainly COULD leak this week, it isn't outside the realm of possibility. But judging other albums and the timeline of when they have leaked within the last year or so, I would say we won't be getting this for another week.
