sperrico, is Pikmin even a system seller?
Is not a huge system seller but can move the market enough when there are few Nintendo games available. I will give you an example/explanation... a lot of people who likes Nintendo games where looking for the Wii U, but the only Nintendo titles available were a 2D Mario than some consider fun but not a must buy and Nintendo Land a mini-game collection, there was nothing else and the only other thing to check out was ZombiU that got decent but not great reviews. So there is a group of people that withold their purchase (I did) till something else that shows promise is available, in my case that game can be Pikmin 3, in somebody else case it can be the Lego title and for others the Wonderfull 101 game.
By itself neither of the 3 exclusive games pending is going to be a system seller (maybe Pikmin 3 can reach 1.2 million sale LTD with luck), but together they can make more people interesed on the system.
