Nintendo president Satoru Iwata recently had a little chit-chat with the Wall Street Journal, letting it know that his company's plethora of purchasable peripherals polluting shelves could possibly slow down. The WSJ points out that Nintendo recently unveiled the Wii Motion Plus and Wii Speak to go with its other pieces of plastic, ready to fill a landfill near you, like Wii Fit, Wii Zapper and the Wii Wheel. Iwata states that the accessories the company originally had planned for the Wii are all out now, but that doesn't mean it's going to stop ... it just currently doesn't have plans to release many more.
Iwata also covers some other items briefly, saying that the company plans to offer the Wii Motion Plus "for as little as possible." Considering it'll be necessary for games like Wii Sports Resort and the absurd amount of money the company is currently making, that seems like a reasonable thing to do.
