We saw Wii U in action for the first time at E3 2011 but the it seems that the console still needs some polishing. Nintendo’s president, Satoru Iwata said in a meeting with the shareholders that upcoming console will be displayed at E3 2012 once again, but this time, it will be the finalized version.
Iwata also told that he has learnt a lot from 3DS’ launch and they won’t be repeating the same mistakes with Wii U. So, Nintendo is in no hurry which actually is a wise thing to do as consoles are not made every year. Wii U is expected to hit stores at the end of 2012.
