Its the next generation of console war between xbox 360, ps3 and wii. xbox360 was released a few months earlier than ps3 and wii. This is the site I found showing the number of consoles sold and wii is currently winning with 50% of the whole sales.
The next generation of gaming is upon us, and the console wars have begun. NexGen Wars.com has spent countless hours researching sales facts from dozens of sources to track the worldwide sales of the consoles and monitor the next generation of console wars between the Microsoft Xbox 360, the Sony Playstation 3, and the Nintendo Wii. Remember, these numbers are only estimates, but they are constantly monitored and updated to assure the closest estimates possible for the Xbox 360, Playstation 3, and Wii.
