[How quickly will tickets sell out considering the line-up?]

Now that the line up has come out, how quickly do you think weekend camping tickets will sell out?

Considering (from what I remember) they didn't until late last year, and T in the Park is still available, however I can imagine Beyonce being a massive attraction particularly to those who missed out on tickets to her arena tour, not that I'm sure this would affect weekend camping as much as day tickets
