Yes I have noticed that and I'm not sure why. Most festivals have their acts booked pretty early, as Beer said above, seems like they start immediately after last year's festival. Even if they are not sure of the complete line up it would be nice if they would list those they know will be there, so that people can make a decision. I usually do want to find out who's going to be playing at a festival before I make plans to go there and it would be nice to know as far ahead of time as possible in case one has to ask for vacation time, etc.
