Satoru Iwata, President of Nintendo, has just announced that Nintendo will not unveil the price or the date of release of the Wii before 2012. This announcement sounds like a first possible delay to the console, which recovered later in the year.
"Since the Wii A that we've shown you at E3 in June is still in development without specific level projects games, we will announce the release date and price next year, when we present these specific titles" . Wii U did so far not game, and Nintendo cannot possibly not submit, and let alone out in trade, a console without games. Another problem: Nintendo must take into account the reactions of the public, mixed at this E3, and somewhat review its communication, and perhaps even the concept of its console.
Of course, the first estimates, who wanted that the console is available for the spring of 2012, likely to be somewhat chamboulées. Nintendo did not leave his console before April 1, 2012, but it appears now that nearest exit from the end of the year is likely.
