Things might change by June 2012

The Wii U reveal at E3 2011 probably didn't go quite as Nintendo had hoped, with some confusion over exactly what the console is and how it works. Nintendo president Satoru Iwata is keen not to make that mistake again though, and has revealed the console will be shown off in its "final format" at next year's E3.

That could mean the machine itself will be altered, or we'll see an official name and some real software for the "new controller", but whatever it is Iwata is determined to show off the console in its best light:
