You were really waiting for iTunes to update? Guys, cmon. We are waiting for the room to unlock. If anything, the room will have the new single and it'll go on iTunes tomorrow at some point. This is Rihanna we're talking about; she never gets maximum amount of sales so of course she'd miss hours of sales for the week by waiting.
Y'all really think she's gonna unlock a room when everybody is either sleep (Europe) or out shopping/spending time with Family? This will probably come tomorrow at around 9AM if anything.. or on a day like Sunday/Monday.
I think the Diary will end on Album release date. This is just a smart way to buy herself time to finish what needs to be done. Im sure she has a release date in her head. (The 4th/11th/18th) But depending on how soon she calls it a wrap on the project. Honestly, Im sure she wants it out just as much as we do. The pressure must be killing her
