I do think in planning the NX launch Nintendo has expressly made sure that this time they have a big time for 1-3 months after the launch period.
They basically are getting a "free" launch by taking Zelda: BotW from Wii U, that will keep Nintendo fans happy/excited for the immediate launch month-to-six weeks.
The dreaded Nintendo drought is the period after this immediate launch though.
I think for this period they already have a game ready to go, so that's why it won't have the same fate as the 3DS/Wii U launches.
What I'm thinking is that the "big" game that normally would've launched the NX (Mario Galaxy 3, Splatoon 2, or whatever) basically now will come 1-3 months after launch instead because they have Zelda: BoTW which takes care of launch (thanks Wii U).
