It's not really doing much for me either tbh. I think it really depends on how big the area is going to be and what characters they want to use.
Do they go in big at at the Studios with Mario and then save the less popular characters for the 3rd hate or do they test the waters first?
The other big point we should be asking, is what kind of image are Ninetendo wanting represented in the parks? Do they want the older games shown or are they wanting this as a platform to showcase something new? Obviously it still has to be popular but do they go with the 8 bit era and GameCube generation or do they go for the shiny new Wii U or whatever console they have in development world on display?
