I know what am I thinking? I think by time Uncharted 4 comes out PS4 will have a much bigger install base than Xbox One. I think that much alone can give Uncharted 4 a shot at selling more than Halo 5. I also think Halo is going to start feeling series fatigue with the release of Halo 5. Regardless both will sell very well. 

Uncharted probably will do better but i think those who play Halo 5 may play it for a lot longer than Uncharted

While I expect the gap to be smaller than it was between the PS3 Uncharted games and the Xbox360 Halo games....no.

Halo 5 attach rate will be like 80%......Uncharted will be like 25-30%...so depending on total sales at that point...

I doubt it. Halo 5 is likely not going to match Halo 3, but it is the "next gen halo" so should manage 8 - 10 million with a big ad push from MS.

I can't see Uncharted 4 selling more than 7 million physical copies. Perhaps it could with a Halo sized ad push from Sony, but that's never going to happen :P

If PS4 gets a good lead over Xbox one, it's a possibility. Halo 5 should win in the long run anyway.

I was originally going to say Halo 5 would outsell Uncharted 4, but then I thought I might as well make a bold prediction.

Halo is a significantly stronger IP sales wise compared to Uncharted... So I will go with no.

Hmm, interesting prediction. It isnt as absurd as a lot of the predictions I see on here. I can definitely see this happening. However, I would still say the odds are in halos favor.

Good bold prediction though. Should be interesting...
