It's the casual end that is saturated with tablets, handhelds, phones and various other devices like android dongles/mini pcs. Powerful dedicated gaming hardware will always be in demand. VR will become mass market and require dedicated hardware.
Nintendo is an established worldwide console manufacturer but their console has sold poorly based on very low peformance hardware but both PS4 and Xbox one are looking healthy and will be much healthier again when they reach a more mass market price.
I think games consoles are here at least for the next ten years and possibly well beyond.
