A professor at Kansas University created a quasi-financial security to try to predict what people really believe regarding whether BD sales will outpace HD-DVD sales in 2007. Basically it's similar to an options contract.
If BD outsells HD-DVD in '07 then your contract would be worth $100. If BD does not win then it would be worth $0. The implication is that if this were an even battle the price of the option should be exactly $50. Instead the contract is currently trading at $82 and has been rising since it started trading a few months ago. Pretty much no one is willing to bet on the HD-DVD side.
