Doesn't really matter what it has or doesn't. We aren't just talking about how well it will sell, but rather how much more it will sell over the PS4 worldwide. How big is smash? Whatever the case is it big enough to make the NS outsell the PS4 by 1M or 2M worldwide?
To put things into perspective..... say the PS4 sells 2M worldwide in all of december. That would mean you are expecting the NS to sell 3M - 4M.
I just don't see that being the case. This is simply because 2M in sales is still very good. The PS4 is still putting up great numbers so for the NS to make any sort of dent in the 2018 year total it would have to do phenomenal numbers. I just don't see that happening.
Maybe next year when/if the PS4 is selling like the XB1 this year.
Here is last year's December (last 5 weeks) according to this site.
I would assume PS4 will be down (PS4 has been down all year long) while NSW will be up (been up all year and Smash will move consoles).
How much they are up/down remains to be seen but I wouldn't be surprised to see numbers like this
