i remember iwata or myamoto saying the always start thinking and working about their next consoles as soon as the launch a new one. and considering nintendo usually goes by a 5 year life span, this isnt something that shouldnt be expected.

why dont you ask your source? 

So Vita TV with PS Now. Following statement is only for your speculation is right: Nintendo innovates while Sony copies!

From what I understand about Nintendo, they never stop designing new hardware. The same way they keep prototyping tons of software ideas and only release the ideas that they think will be cheap to develop into a full game and be appealing to broad base of potential gamers.

That's pretty much obvious, probaby Sony and MS would do postmortem analysis this year and will starting developing some hardware in 2015-2016. Hardware development takes time, so you better start early.

He's switched jobs, so he can't tell me that stuff anymore. But I'll ask him next time I talk with him ;)

Despite what this report says is bogus, the affirmation is kinda obvious, they probably started discussing ideas before the Wii U was even released, that's not new, it seems a lot of people don't ''get'' this console development thing haha

Of course they are, the hardware guys don't sit idle after systems come out.

The more interesting thing is what is it, and when will it come out? I think sooner rather than later. The mobile market is putting real pressure on Nintendo to make something innovative and cool for the kids. I think this new handheld will break from the mold of the DS/3DS and push into tablet territory with a much higher resolution screen and numerous "apps" that kids will love.

Any talk or traction of a new system in development will only cause further declines in current gen hardware for Nintendo, especially as the new filters through to non forums etc.

This ^^^

All 3 platform holders start working on their next console when their current console has been released, even before sometimes.
