considering the Switch is KIND OF A LITTLE BIT like an affordable tablet dedicated to video gaming that can be easily translated to home use too..... they were probably worried that Sony and Micro would jump onto that quickly to counter Nintendo
bear in mind both Sony and Microsoft already create LOADS of electronics, well maybe Microsoft is more on the software end of things with electronics, but still.
it wouldn't be crazy to think that if given enough time they might create a similar minded attempt at a device. we saw it with the Kinect attempts my Microsoft after the Wii
Nintendo just delayed announcing to cover their bases. even now they've still been quite vague on some details though so there could be something else involved, I don't know
