If this ''soon'' that Iwata said has any weight and is not just some corporate bs to keep us happy like most of what CEOs usualy say, then I expect that reveal to occur in a Nintendo Direct during or near the holydays shortly after the launch of WW:HD. This will help reminding or convincing ppl that WiiU is a good investement over the competition for the holydays.
