I'm not surprised to be honest, I think they're just too damn expensive.

Even mediocre seats are $500 and with the shit £ rate it's just not economical. I've got a hotel and flight to Vegas for £460, I'm not willing to spend almost the same again to watch the fight. I'm just going for the weigh-in, atmosphere and to see it in some bar or on a CCTV screening.

Calzaghe Vs Hopkins was similarly overpriced and half the arena was empty. I can't imagine this fight will be like that but the economy and price of tickets explains why it's not sold out.
