Tagging. I think 2018 might be Amazon's fail year. I'm beginning to think the Switch demographic does a much larger amount of online buying. Meaning that even months where Big games and offers come in, leading to a PS 4 NPD win, it will still show different on Amazon.
I expect the Npd wins to be close to 50/50 between Switch or PS4 or a close Switch win. But I'm expecting Switch to take 11 out of 12 months on Amazon. We will see over the year though. I'll be glad to be wrong on this prediction.
Interesting you think Switch will win SO MANY months, yet you believe Switch and PS4 are gonna be close.
Personally, i expect Switch to win by a pretty massive lead... but we'll see.
