Satoru Iwata, Nintendo president: "If it is predetermined that the hardware price shall gradually decrease, then that model reiterates the notion that early purchasers will suffer a loss, which I do not believe is the right business model.

"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
