Okay I know, its earlyand I never thought it was possible but after seeing the debut of halo 5 in the uk , i realized i think the halo behemoth isn't as popular as it was , and ND is extremely popular this gen, so could uncharted 4 first week beat halo 5s ??
note halo 3 on xbox 360 released on a similar install base as halo 5 on xbox one , and still sold 3.3m first week ( sold like 370k first week in the usa )
i think halo 5 will sell 1.9 to 2.1m first week
uncharted 4 2.4m to 2.6m
lifetime i'm pretty sure uncharted will win due to difference in install base so its strictly first week sales
