You're projecting here. Wii U is doing poorly because it hasn't attracted publishers, which is most likely due to design issues and the fact that Nintendo has a stigma as a casual gamer's company. Quite simply, there's no games for it.

In terms of the PS4 and 720, they just were announced. You can't say that people aren't buying something they can't buy. Frankly, the DRM argument you are making is grounded in nothing right now.
