I suppose if Uncharted 4 is bundled even more than Uncharted 3 then it'll have a chance at 8m+... Halo 5 will probably do 9m+ though without even needing much bundliing because it's a far more popular IP, so nah, won't do it.
A series like Uncharted depends solely on the mass bundling for huge 6m+ sales, it's a fairly popular 4-5m franchise otherwise but still nowhere near GT, GoW or TLoU polularity, so I think a sequel to any of those series with mass bundling has a better chance at topping Halo 5.
