The different motion control systems in the market

Hello.On November 18, Microsoft released its newest gaming product, the Kinect for the Xbox 360. With this release, it became the third player in the motion control system market,after the Nintendo Wii and the Playstation Move.
History of the motion control system players
It all started in 2005, when Microsoft released the Xbox 360 console .The seventh generation game console era had begun. Playstation replied with the Playstation 3 in 2006 which was similar to the 360, a console with a normal controller.  Nintendo did release their console too in 2006, it was called the Wii. However, Unlike the PS3 and the 360, the Wii was slightly different.The Wii controller required people to move the controller instead of just pressing the buttons. This was something new, and unsuprisingly, the Wii had the best sales of the three consoles , selling 75.9 million units as of September 2010, compared to the 44.6 million for the Xbox 360 and 41.6 million for the PS3.

The Kinect is doing very well currently, with news constantly reporting the Kinect being out of stock.

Now i can't really tell you the pros and cons of each system, but i can give some advice.Firstly, if you have a PS3, jus stick to the Playstation Move.Don't buy a new Xbox console just for the Kinect(Unless you are rich). If you intend to buy a console and love playing games like  FIFA 11 as well as Kinect-type games,don't buy the Wii.(FIFA does not operate on the Wii.
