Shigeru Miyamoto said:Originally, I was making Pikmin 3 to be launched on the Wii platform. Because the Wii U is capable of HD quality pictures, and will be accompanied by the subscreen on your hand. I thought that I would be able to make a Pikmin that was closer to my ideal. I am now actually enjoying myself, working on the game.
Source just has some brief and irrelevant commentary
This is great news. If he's enjoying working on it, that probably means it's coming along to his full satisfaction. And as much as I always stress the relative unimportance of graphics in a game, Pikmin deserves all the polygons it can get. Can't wait.
