On what grounds?

What makes you think God of War won't be bundled as well? It's happened plenty of times before. I mean Horizon just sold over 4M in less than a year. Let's not pretend Horizon is a bigger franchise than God of War.

I'm not pretend anything. And if Sony is smart, they will bundle GoW. But the fact is U4 has a ongoing bundle since forever. I doubt the will do the same for GoW. 

hard to say, 2 completely different things, but at the start god of war will make the race

Labo will sell way more, especially in the long run. That new GoW doesn't look very exciting tbh...

the fact that this is actually not a troll question is sad....

Thats a estimate of retail sales (4.2m)... includeing digital too, and its probably over 5,5m (going by these vgc numbers for it).

Labo should see much higher sales over the short term. There are a bunch of different SKUs with more probably planned so the comparison doesn't make a lot of sense, to be honest.

If Labo turns out to be some cheapo mini-games tethered to a pretend "crafting" gimmick then I hope GoW beats it in the long run.

Thats def. the vibe I get from it.
But since its ment for a younger audience it doesnt matter.

Kinda hope theres more core gamers out there, that support GoW than Labo too.

God of War will definitely sell more first week. But Labo will probably have better legs and outsell it after a year or so.
