Nintendo is doomed every generation, by the same people who were sold an XBone by this conference. I've said it before and I'll say it again:
Nintendo are growers, not showers. You get their systems for a small handful of masterfully crafted first party games each year, and by the end of each year your collections for competitors may be larger, but there are far more classics from Nintendo.
Also E3 has never traditionally been where Nintendo drops its bombs. They take care of their home front before they worry about America.
