It's funny that investors wonder how the Wii U will compete with the iPad and smartphones.... when it is is no way competing with them at all. The Wii U is mainly going to compete against the Xbox 360 and PS3, yet the Wii U offers more gameplay variety, more processing power, and Nintendo games.
Gamers are excited, investors are dumb and out of touch. This will be proven upon launch next year.
You can only use one of the fancy new controllers per console (everyone else has to use a Wiimote). They only thing they showed at E3 was the fancy new controller. Do you think a parent with multiple kids is going to buy the WiiU then deal with endless arguments over which kid gets to use the shiny new controller?
I'm very curious myself. I personally was very excited about the Wii U announcement. Although the concept is in infancy the enormous amount of innovative gameplay experiences that could be possible are still unfathomable. I suspect someone or something is driving down the price for a huge buy. No other reason it should have gapped down it seems...
