I roll with Sony and don't bother with other platforms, but I expect the new Zelda to be a bigger seller of the two, at least for the first couple of months.
1) Horizon is a new IP that has yet to prove itself, this always creates uncertainty and people will wait for first impressions, reviews and what their friends have to say about the game first. Zelda is a huge and long standing franchise and people know what they're in for and what to expect. To Nintendo fans, it's something of a holy grail.
2) Nintendo machines don't really have anything else of note to offer at that time, especially the Switch being a new machine, so all Switch buyers will go for Zelda right out of the gate. PS4 has so much stuff going on all the time and people probably have backlogs to go through as well. They have a wider choice of games on offer, both 1st and 3rd party, and Horizon is just one of many attractive options to get into.
I believe both games will be successes and sell plenty, although Horizon will be more uncertain. It's always a massive task for a new IP to establish itself.

OP - Horizon will sell more than Zelda, Zelda will get a better metascore.

Going to be interesting to see how both games will perform. Looking forward to that week!

And ?

How am i downplaying the ps4 ?

What has the ps4 sales number to do with how much people will like horizon ?

Explain to me

Zelda BOTW will sell more on Wii u than Switch, and nobody is counting that, thats all. Nintendo games have an insane attach rate on Wii U, so Wii U version can makes a difference, big difference. Still, somehow I fell that Horizon will sell more. Playstion is just in .. another league in comparison to Nintendo now.

BTW - confirmed PS4's sales is 53.4 - latest Sony's annoucement at CES.

I found it on google and was never able to find its source. I think it might be fan art... I'd love to credit the creator but I can't find them.

1. CES number is for 1 January 2017, consoles sold to consumers already.

2. 51.20  is the most accurate number i get from the internetz.

And 

Zelda has something that horizon doesnt 

And that is nostalgia 

People buy nintendo games not because of hype the buy them because of nostalgia and fond memories they had in the past 

So lets see which one will be successfull

What

the

heck

with 

u ?

Im fine 

I think something is wrong with you
