Is it really the wiiU who performed poorly? Or are we just starting to see the beginning of the end of dedicated gaming consoles?

I am interested in reading all of your opinions.

EDIT: I meant can the poor performances of the wiiu be explained by the fact that people aren't so much interested in next gen dedicated gaming consoles.

Its really just the WiiU for now, the other 2 consoles haven't come out yet.
