Just read this intersting article : http://techland.time.com/2013/01/30/are-weak-wii-u-sales-a-bellwether-of-shifting-game-demographics/
The WiiU is said to have sold 3 million from end november to end december worldwide, but Nintendo lowered their prediction of 5.5 M at end of march to 4 M, meaning about 1 M for 3 months!
I'm getting anxious that, with the help of casual gaming (smartphones, tablets, Wii) a big majority of people don't care about home consoles anymore and won't spend 100s $ when they can have fun with a 5$ game on their tablet.
With Sony buying Gaikai tahy can sell all casual games and people can play them on the cloud, so maybe no PS4 at all? or a gimped console that can just run Gaikai?
