Personally, I suspect that the bargain bins lead to underestimations of all of the system's yearly software sales; and (to a certain extent) this underestimation could hurt the Wii and the DS more than the competition. There are (probably) hundreds of games that (probably) sell between 500 and 5,000 units worldwide on a weekly basis that are (probably) not tracked that well because of where and how they're sold. When you add up all of these units it potentially adds up to millions of units of software sold for each system that is simply untracked.
