I could see Nintendo releasing their next home console before the others, but probably not as early as 2017. We haven't heard word of a successor to 3DS yet and I think that'll come first - probably announced next year at the earliest and released around 2017.
An educated guess would be a new home console around 2018, maybe even 2019. They might do an upgraded/more powerful version of the Wii U in the way that they've done with the New 3DS but I doubt we'll see a full-fledged new home console as early as 2017.
