Natal and Wii are NOT proven at this point. To understand this, calculate the total cost of getting Move, compared to what you spend on the Wii, and then see if people would be willing to pay that. Factor in also the cost of a PS3. Maybe the controls work, but proven as far as sales go, it isn't. As far as Natal goes, it is even LESS proven, but apparently Microsoft was able to generate a buzz about a game with no controls being real cool.
This is the case of that which is not known generating more interest than the familiar. People are watching Natal to see if motion-control becomes all that. With Move, it what the Wii does, but at a higher price point. Maybe it does it better, but it looks like what has been seen before, and thus not as newsworthy.
