He doesn't really say that its cheaper than the competition, does he? It kinda depends on how they view the tech themselves, they're probably thinking that Kinect is more bang for the buck than simple controllers you wave around and a statement like "very pleased with out position" is cryptic and unintelligible at this point.
By all means, it could cost around 100$ for all we know but I somehow doubt it, especially seeing the price of the upcoming slim bundles and adding the fact that games and gear always comes cheaper in bundles.
We'll see. In the end though, it doesn't matter a whole lot for me, I won't be getting neither Kinect nor Move any time soon. Could prove to be entertaining watching reactions when it does release though and I am genuinely excited about how it will perform on the market, Kinect and Move will likely help set the premises for MS and Sony's next generation of hardware!
