Nintendo's showing at E3 yesterday didn't satisfy investors it seems.

While the unveiling of the Nintendo Wii U got the industry talking yesterday it seems investors were not so excited. Bloomberg report that Nintendo's shares fell to the lowest point that they have been for five years.

According to Tokai Tokyo Securities analyst Yusuke Tsunoda the announcement failed to raise excitement as it merely confirmed what had long been speculated. Speaking to Bloomberg he stated: "People had expected to see something more at a big event like the E3, but there wasn't really anything more than what's already reported."

At the close of trading yesterday in Osaka Nintendo had fallen 5.7 percent to 16,930 yen and more than 2.2 million shares were exchanged.

We will have to wait and see whether or not shares will increase once Nintendo announces more details, whenever that may.
