In terms of amount of software sold Nintendo will absolutely destroy Microsoft and Sony and most if not all other publishers out there in 2019. I think they will just edge out the Hardware side of things as the Switch is just hitting it’s stride now whilst the other two are in a natural decline.
Animal Crossing alone will outsell TLOU2, Ghost of Tushima and Death Stranding “combined . I’d be willing to put a 100 on that now, not to mention the Switch has about 10 other huge exclusives on the way.
This is a sensible prediction from a neutral, analytical point of view. They will dominate software sales and comftorbly win hardware sales.
