theirs two possibility that the WiiU will still sell's way more than ps4....................and its not hard to make games since 360 and 720 use the same GPU on the WiiU
Wii will sell more than 100 million by 2013
PS3 will overcome 360 by 2013 by 720,000+ with the ban on 360
360 will be the best performer console but will never beat sony...sony has lots experienced with the console business not making best hardware but with dirty strategy that killed SEGA dreamcast will do the same on 360.....and 720....they done it before will do again......they don't like to be 3rd place...
