If Sony had any sense they would flood the internet with multiple fake leaks to frustrate those looking for the real deal.
For example, Sony could leak 100 different fake leaks with different track lengths, sizes etc and then fill the comments sections of each torrent site with reviewers saying all the leaks are real, it might make downloaders get fed up with it and give up. They could also find the real leak(s) and add multiple reviews saying it's fake so downloaders wouldn't know which ones to download to get the real files.
They could do the same on Usenet too - if a 'professional' pirate leaked the album, that's where it would appear first (it's not there at the moment). Torrents are often started by 'amateurs'. Considering the album is about to ship and loads of people are going to have access, it may well appear on Torrent sites first.
Sony have done well to prevent leaks so far, but from this point on it's inevitable.
