Nope, Xbox is on decline and Halo 5 would have to outsell Call of Duty:AW & Black Ops III and become the best selling Xbone game to beat Uncharted 4 lifetime. Uncharted doesn't even have to be in top 5 (at the moment) to beat COD:AW numbers and it has the advantage of larger userbase and the fact that 60%-75% of Halo 5's sales come from North America, which was the area where PS3 used to struggle against X360, however PS4 is evenly matched with Xbone in NA.
The point is that Halo has to be the best selling Xbone game by a big margin, but Uncharted doesn't, eventually U4 could drop out of top 10 PS4 games and still beat Halo 5.
That being said Halo 5 will beat Uncharted 4 in NA.
