Two things: price and software
Just see the example of every recent console launch: Ps3, Xbox360, 3ds, Vita all had slow starts and didnt start to sell well until the game library got bigger and the price got lower. It´s not being different with the WiiU.
Besides die-hard fans, most consumers are not willing to pay big money on consoles anymore, so I expect both PS4 and XboxOne face the same pattern.
