TOKYO--Nintendo president Satoru Iwata revealed that the company is aiming for a simultaneous worldwide release for its next-generation gaming console, the Revolution. Iwata also confirmed that the system will be coming out after March in 2006.
"It [the Revolution] would be a complete failure if we didn't sell more units than the Nintendo GameCube," said Iwata.
