Not sure how I would categorize it.
Concept in the planning for the hardware design, but execution in the implementation of it. I don't think the Wii U Tablet controller is a problem. In that regard, I think Nintendo had a great concept and great execution. The problem, as I see it, is the console itself. Nintendo has been able to get away with less powerful hardware for sometime, but the weaker hardware and the fact that they're so far behind both Microsoft and Sony with their online service may end up putting them too far behind.
In terms of games, clearly execution.
