I'd say no, but I think internally Nintendo is likely fairly unhappy with going from 150 million DS to only about 70 million 3DS' probably and having to have a couple of years of losses to even get to that 70 mill-ish as is.
Like I don't think they're exactly popping champange bottles over in Kyoto due to the 3DS. I think they're also extremely concerned by the erosion of the handheld market, moreso than anything to do with the Wii U, I bet that's the issue that keeps them awake at night.
If the handheld market continues to shrink they could be in big trouble going forward.
The smartphone/tablet conundrum I think is driving Nintendo nuts internally. I don't think they know how to deal with it, competing with Sony/MS is much more straight forward and predictable, smartphones/tablets are eating away at Nintendo strongholds in a way that I don't think they've ever faced. Sony just got obliterated out of the handheld business, Nintendo is hanging tough, but this is very definitely a dog fight now and they are taking heavy fire.
