Todd Bishop at the Seattle Post Intelligencer has pulled together some interesting data about how the Xbox 360 has impacted video game console sales. By pulling together publicly available data for a few of the largest game publishers, one can get an idea of how the Xbox 360 market is shaping up. This isn’t going to be perfect because first party sales figures aren’t going to be reported and there are many other game publishers that aren’t represented on the list. Also, because not every title released on the Xbox is available on the Xbox 360 and vice versa, there are going to be some gaps in reporting in this area as well. But this does give a really high level view of the console market, and how marketshare is shaping up.

Over the first nine months, it appears that most of the Xbox 360 marketshare is coming at the expense of owners of the original Xbox. A small percentage of Playstation 2 sales appear to have shifted to the Xbox 360, but overall, the console still remains the dominant force on the market. Gamecube sales dropped off, but this may have had more to with the fact that fewer titles are being released on the Gamecube than on the other platforms. Total sales of game titles released for either the Xbox or the Xbox 360 grew year over year, but this may be in part to the 20% premium that Xbox 360 titles claim over their counterparts.

Despite all of the limitations of the data pulled, this gives a really interesting look into which consumers are pursuing platforms. With the Playstation 3 and the Wii releases coming up, one wonders how much brand loyalty is going to play into the success of the next generation.
