I have followed this chart in the past....but I think the data is either wrong or way off.
For instance, one game I am following is Final Fantasy XIV. If you look at it's page on here....it shows really virtually no preorder data for 2013 (only for the failed release a few years ago). If you look at the hype surrounding this game...it's starting to blow up. Plus, on the Amazon charts....it's in the top 50 in both PS3 and PC versions. I don't see how this chart is accurate if it's not on it (plus the page for the game must be wrong with virtually no preorder info)
