In the interim, several blogs, the winediarist in particular, have held long and fairly tedious chains of comments about the study by people who have clearly not read it and do not understand statistics.
Here's my problem: it's a small bore student paper that sticks closely to it's data, applies the wrong test, but most importantly, doesn't appreciate the role of pricing in an economic system.

If you want to to measure point systems against release prices, well... that's another story... one that has nothing to do with consumer attitudes, but it might be interesting.
