OSAKA: Nintendo Co Ltd will launch a successor to its aging Wii game console in 2012 as it bets on a new hit games platform to win back users lured away by rivals Microsoft and Sony , and reverse a fall in profits. The maker of the DS handheld games device, which is also facing competition from smartphone makers including Apple Inc , said Monday it will demonstrate a prototype of the new Wii in Los Angeles on June 7 at the E3 game show. Nintendo is looking to repeat past successes in the gaming market. The Wii took the industry by storm five years ago by offering family games such as tennis and bowling that appealed to non-traditional gamers.
