They say it can sell at the same level or close to Uncharted 4 and Metal Gear Solid V.
Look, I'm no expert. I'm just looking at the game titles here.
You know, there's a reason those games sold well. They have fanbases.
I don't doubt Horizon will sell very well, but I can't see it topping 6 million. Not at all.
Not likely, but idt it's impossible. TLoU sold 7-8million on PS3, right? And this was despite PS3 having a poor userbase in the US and TLoU releasing at the end of the 7th gen. Ontop of this, PS4 exclusives and games sell well far more consistently than those on PS3 ever did.
