Yoshiaki Koizumi, the director of Super Mario 3D Land on the 3DS has admitted that he has “too many ideas at the moment for Mario games on Wii U.”
I’m going to have to start narrowing them down and thinking about which ideas might work well together so that the whole system will be an enjoyable experience rather than a hodgepodge of ideas.
This probably means the first major Mario title on the Wii U will be packed with a bunch of crazy ideas. It also means we shouldn’t expect to see the game at the launch of the Wii U. It could take a couple of years.
