What's price protection? Price protection occurs when a publisher of a game that isn't selling offers its game to retailers for a lower price, allowing stores to get rid of excess stock quickly. If this happens too soon (EEDAR defines "too soon" as "when a title's third month average selling price has decreased by 20% or more from its original average selling price"), it is known as "early price protection."
Anyway, EEDAR found that 15.1% of all Wii software goes through this process, compared to 7.5% on Xbox 360 and 9.09% on PS3. What does this disparity say about Wii software? EEDAR analyst Jesse Divnich thinks it backs up the theory that third-parties struggle on the Wii because they and retailers have "overly aggressive expectations" for Wii games, and that it proves "quality is one of the most impactful features for a video game."
Or, in a nutshell, Wii has waaaay too much half-assed shovelware.
