This is in line with my expectations from the start -- that they'd have a year or two of mostly sold out dates, then need to lower the price or just offer some discounts going forward.
Of course, that depends on if they care about selling out. They could still be making money on dates that are only 50% sold. They may prefer to keep the current pricing as long as possible regardless of sell-outs.
I'd definitely be interested in knowing what capacity is their break even point.
