After Nintendo announced Wii U at E3 yesterday, share prices for the firm were the lowest in five years, according to Bloomberg.
Nintendo stock fell 5.7 percent to 16,930 yen at the close of trading in and over 2.2 million shares changed hands, compared with the six-month daily average of about 720,000 shares moved.
"There were high expectations from the new version of the Wii and this fell far short," said analyst Yusuke Tsunoda. "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."
Yesterday, Iwata said Wii U will likely cost around $250 in Japan next year, said Japanese newspaper Nikkei.
