I personally like the Wii, as it's original and led to this new era. But having played the Wii, I found there are a LOT of flaws in it's design. Still a good thing though, esp. since it's a full console, unlike Sony and Microsoft's inventions.
However, I absolutely love Kinect. After watching it numerous times in action, it just looks plain amazing and revolutionary. I can see a lot of potention for gaming with this new style of technology.
So basically... Kinect is in the lead (imo), with Wii just barely behind. As for Move, it's just a bad run-off of the Wii.
