What will be the 1st 10 million seller of the 8th Gen? (Home Consoles only)

[Bokal]

I'd say none of these games. Maybe later in the gen.
The install base is too small yet.

Halo5, CoD 2015 and UC4 should get close.
CoD 2016 with install bases around 50M could achieve it if people don't get bored of it.
