No, I don't see it effecting Switch's success.
The Switch is a portable unit, primarily geared towards gaming, while mobile phones attached to the cloud are primarily designed around making calls, videos, texts and some general purpose apps, and then a small bit of gaming.
The Switch has already proven that there's still a userbase to cater towards, and so far mobile gaming hasn't really butchered it, and so far neither has Stadia, so I don't see Amazon doing it either.
My main concern is if Amazon does gain ground, and Stadia improves, then MS releases theirs, that we'll start seeing more competitors entering the ring. The last thing I want to see is more and more companies gearing up for pure cloud gaming, because I know normies will eventually just mass adopt that over time.
Switch is fine for now, but I think if Cloud gaming really manages to take off proper in a few more yrs, then gaming as a whole is going to evolve to that end point; always online gaming rentals, a gamer's worst nightmare, and a publishers orgasmic wet, long lost dream.
