Are you saying that Mario won't even barely move the sales numbers?
You are saying that people won't buy the Wii U because the other platforms have other games. That is wrong. If "no one" are going to buy a Wii U for Mario, Zelda, Pikmin, Metroid, Star fox, F-zero, Xenoblade, Endless Ocean, Fire Emblem or freaking smash bros, then who are going to buy these systems for a rather small title (compared to nintendo's bigger ones) like Killzone?
