I feel like Uncharted 4 outselling halo 5 is all but guaranteed at this point. U4 is looking to be bigger than ever. It's amazon preorder sales have already surpassed the division's (and all other 2016 release games') cumulative sales since March. Halo 5s sales are good in their own right, but they are not even on track to surpass U2's or U3's sales.

I personally predict that U4 will sell at least 8 million, but I think 10mill is not completely out of the question. One thing I didn't see mentioned (tho I didn't read every post) that will help U4 significantly is the much larger US install base/popularity for the ps4 compared to PS3. For various reasons I think this gives U4 a chance to really break out in popularity and sales.

Uncharted 4 is going to do it this time around even if Halo 5 is the biggest X1 exclusive

Uncharted easily, the userbase difference pretty much guarantees it.

This right here.   It just makes sense.

Even if Uncharted has a 5% lower attach rate, its still a massive blowout victory for Uncharted 4.

And anything above a 20% attach rate would make it so very improbably its not worth talking about. 

Halo 5's chances of winning this match up are about as good as its chances of winning OP's poll.

I would say less

The number of people who believe that Halo 5 will outsell Uncharted 4 is higher than it should be, is 8.5%+ over 40 people.

I don't think some people realize that Uncharted 4 is on pace to sell about half of Halo 5's total sales in its first week.

It had over 700K predorders in the US alone.

It'll be fun to track U4 sales. 

Someone threw out a 10m figure that feels like they pulled out of their butt given that U2 did about 6.7m and U3 did about 6.8m, but it would be really nice to see U4 as a capstone for the franchise beat those numbers. 

I think most will accept it's a given U4 will outsell Halo 5, so at that point this thread should be more about how U4 does as a metric to measure PS4 attach rates for big franchises such as Uncharted as well as to track whether the franchise itself has peaked or still has plenty of gas left in the tank. 

Hmm...No really, just look at how Mario Kart is performin on its small user, look at how Halo 2 performed on the original Xbox. Uncharted 3 had a hugw audience but could never crack 8m. 

Uncharted 4 may surpass Halo 5 in the 1st 3 weeks.
