Nintendo has announced that they hope to showcase the Nintendo Wii U's final form at next year's E3, a year after the console was announced to the world.
The statement was made by Nintendo's CEO Satoru Iwata while he was speaking to investors. He stated that Nintendo has "learned a bitter lesson with the launch of the Nintendo 3DS."
This still issues no firm release date for Nintendo's next home console, but they always stated that it wouldn't come out until after April 2012. Now it looks like it will launch post-E3 2012.
