$50 is probably a stretch in a lot of cases, but that's another issue.
Also, when comparing buying books versus buying games, I think the demand for new game titles is usually a lot greater than most of the books that are released. Also, far more books are published weekly than games, which probably helps to lessen the demand for all but the biggest books (like your Harry Potters). I think the markets are similar in some regards but too different to compare when talking about whether pre-order systems are effective or not.
