If this mysterious new stage is more geared towards EDM output and visuals (i.e much bigger screens) then it would make sense to shift Anyma to that stage.
That said, I can't think where they would put the stage to make it big enough to handle the audiences of Anyma and Justice. Plus, surely they wouldn't have main stage empty at 10pm on a Saturday night?
Does anyone happen to know the exact date the new Pyramid Stage was opened in 2000? Around Easter time I think? It was apparently baptised with a pail of Worthy Farm milk by Robert Plant and Michael Eavis.
We should send a birthday card!
