In Nintendo's 72nd shareholder meeting, Nintendo President Satoru Iwata expressed his grief over the stock media, and how analysts portayed Nintendo as lacking confidence in its product, that being the reason for the unannounced price and release date. I'll let you read it for yourselves:
" Among some news reports, a report I was particularly disappointed with was that the announcement of the launch date and the price (of the Wii U) was postponed. We made a statement in public before E3 that we would announce neither the launch date nor the price (of the Wii U) at E3. It’s nothing new at all because, when we introduced the Wii, the Nintendo DS and the Nintendo 3DS, we didn’t announce the launch date or the price at the E3 shows, either. Nevertheless, what was reported in the media was that, in the context, postponement of the announcement regarding the launch date and the price was due to lack of confidence. This type of news somehow affects consumers’ minds and that would have had an impact on the share price as a result."
