And this year it had Heaven & Hell, Dream Theater, Queensryche, Edguy, Saxon (although their bus broke down and they cancelled), Down, Blind Guardian... I don't see a problem.
It was also in a smaller venue (last year was Arena Parc Nord in Bologna), and only two days instead of three. So by definition there'll be less money to spend on bands... and they still got four headliners.
