Kojima discusses the differences between PS3, 360, and Wii
“The PS3 is like the theatre, it’s a little bit high-priced but it has to be high quality as well. The 360 is a DVD, it still needs to be high quality but you need more variations, while the Wii is almost like a TV channel, because every game you have it with your family”.
Another variation on something Kojima said awhile back. My personal favorite was when he compared all three systems to types of food.
