The researchers at Electronic Entertainment Design and...Research have been looking at console game sales patterns. Looking at how long it takes a game to enter "price protection", which is a term used for when a publisher - having noticed a game isn't selling very well - lowers the wholesale cost of a game so that retailers can keep it on the shelves at full price, even when the public are ignoring it. What they've found is that this practice occurs for 7.5% of 360 games. And 9.09% of PS3 games. But the Wii? It happens for 15.1% of titles.
