Looking at Nintendo's stock, it appears the tremendous success of the Wii and DS have essentially evaporated overnight. Shares for Nintendo closed down 13%, and were down as high as 20%, after Nintendo released its disastrous financial report, largely blaming sluggish 3DS sales. The company immediately dropped the price on the 3DS, and is now expecting an 82% drop in profit for the year.

Shares for the Japanese video game company haven't been this low since 2006--before Nintendo launched the Wii, and spurned a massive turnaround for the gaming giant.

The Wii U controller is not unlike the 3DS. In spite of significant advancements made to capacitive screens (like the ones used on most touch screen phones and tablets), both utilize resistive touch screens that work best with a stylus. There may be a reason why the two systems are so similar. Nintendo president Satoru Iwata revealed that the 3DS can act as a controller for the Wii U. "It is technically possible," he said at Nintendo's recent investors meeting. "However, there are some limitations: While the Nintendo 3DS is communicating with the Wii or the Wii U, the Wii or the Wii U will not be able to access the Internet, and this technical restriction will remain unless we add some special hardware."

"Some consumers might feel that Nintendo is saying that consumers must buy both systems," Iwata explained.
