The successor to Nintendo’s hit Wii console will arrive next year, Nintendo said yesterday. The company didn’t say what the new system will do, but plans to show a playable model of the new console at the Electronic Entertainment Expo, which runs June 7-9 in Los Angeles. Nintendo sold 86 million Wiis since launching it in 2006. The Wii caused a splash with its innovative motion-sensing controller. Sports-style games such as baseball and boxing lets players move their arms to simulate the pitching of a ball or the throwing of a punch. Nintendo also makes a step-board accessory that allows players to dance or do yoga.
