I appreciate the effort put into this data-gathering, but I think it's way too coarse to make it useful in predictive terms.
The obvious problem with categorizing the data by console is that the three platforms have very different library compositions, especially the Wii vs the PS3/360.
As such, trying to predict anything about the long-term sales of a game based on its initial sales on a given platform will be totally unreliable unless the game is homogeneous in genre and target audience with the majority of the console library.
An analysis with real predictive power should try to model the sales of games in a parametric way and gather average parameters for the various genres/contexts.
