"Nintendo's philosophy is to try to create new forms of entertainment"
Nintendo's veteran games developer Shigeru Miyamoto has told the BBC that the firm is "not worried at all" by Microsoft and Sony's new controllers.
The Japanese firm has enjoyed huge success with its Wii console, in large part due to its motion control system.
At the E3 games show in Los Angeles, both Microsoft and Sony have shown off new control systems which aim to make gaming more accessible.
Mr Miyamoto said Nintendo was flattered by the approach taken by the firms.
He told BBC News: "The fact that both of those companies are looking at getting the gamer off the couch, taking advantage of motion control, and getting them to control the game by moving their body shows that they have looked at what we have done with Wii.
