Highly doubt it. I don't think a 100+ year old, multibillion dollar company is scratching their head and sweating buckets about their product. They've been talking about it, other companies have been talking about it. They've spent years of R&D on it. NX development began literally the day the Wii U released. I could probably find the article that had Miyamoto and Iwata saying they're already thinking about the next product.
So they've had time to work it out. They've had time to develop NX in reaction to what they saw with Wii U. It's not the right time for them. Humiliated by Wii U's launch, I'm sure they're trying to make sure the same thing doesn't happen again. Almost all of Nintendo's muscles are being flexed on NX software, if the software isn't complete by the time NX is supposed to arrive, they're going to delay it. Nintendo not speaking about NX is mostly a software thing, I think than hardware.
Reggie, Iwata, all of them have made sure to say that Nintendo isn't pursuing graphical power for their next console. Anybody can do that. Any company can just pay AMD or Nvidia to make "more", as long as they're willing to pay"more" and that's not NIntendo's philosophy. They've always been about minimum input for maximum output. That's the essence of Wii and DS. Making great, simple, yet effective software on solid and purposeful hardware. Where Wii U went wrong was, the Gamepad wasn't purposeful, and the Wii U as a whole was too expensive.
I think NX is being kept a secret simply because Nintendo wants this thing to come out not only guns a blazing, but to have many more games down the horizon. Even to the point where a game by Tokyo NPD is out at launch, but Tokyo NPD is already in mid development on another title.
