There was a lot of buzz over the weekend as news broke that the Microsoft Kinect was outselling the Playstation Move by a ratio of five to one. But the numbers aren't quite so simple.New numbers dropped Friday night showing that in terms of bundled units -- that is, new consoles that come with the motion-gaming accessories -- Microsoft is outselling Sony five to one.

Bundled numbers are important. After all, they may show how many consumers are buying consoles as a direct result of the new technology, but they aren't a good indicator of overall sales, since many people who already own consoles are likely to upgrade.

Further complicating matters, the XBox 360 Slim hit the market over the summer. So it's hard to parse who's buying for the Kinect and who's been saving their money for the sleeker, shinier model.

The reported figures on peripheral sales also muddy the picture. Sony reported that it's moved 4.1 million units to stores between its Sept. 17 launch date and Nov. 30, but the company did not supply actual sales figures. As of the same date, Microsoft reported the Kinect had sold 2.5 million units globally only 25 days after its release.

No matter how you slice the numbers, however, things don't look great for Sony. After all, logic dictates that the figures should slant in Sony's favor overall, since gamers need one Playstation Move controller per player, as opposed to one Kinect per console. And regardless of which console wins this match, it will still be a battle to claim the motion-gaming belt from Nintendo and the family-friendly Wii.
