Instead of guessing software/hardware data for a region, guess when and how much a console will see its price dropped. Data would stay up until the next price drop is announced. For instance: PS3 - $500 or $600 I predict the price drops in April 1, 2008 to $400 or $500. The price drops to $350 and $450 on June 1, 2008. So I would be off by 2 months (months off could be on a points basis, with 0 months off being 10 points, 1 month beings 9 points, etc.), and $50. For every $50 off, you could be docked in a similar manner to time. It would also be possible to update the predictions league to estimate how sales patterns change after the price drop.
People are difficult to govern because they have too much knowledge.
When there are more laws, there are more criminals.
