The PS4 currently leads the pack with 3 games selling over 10 million. Uncharted 4 is well on it's way to becoming the 4th. Xbox One hasn't yet and the Switch has just recently launched. So I wonder what games on each console are going to sell over 10 million eventually? These can be games that are already released, announced or aren't yet announced but are obviously coming, like GTA VI, Smash Bros Switch etc. 

I'll start:

PS4

• Grand Theft Auto V                  - 22 million
• Call Of Duty Black Ops III        - 15.8 million
• FIFA 17                                        - 12 million
  
• Uncharted 4                               - 12 million
• Star Wars Battlefront               - 10 million (Maybe)
• Star Wars Battlefront II            - 10 million
  
• The Last Of Us Part II                - 11 million
• Red Dead Redemption 2          - 12 million
  
• FIFA 18                                         - 13 million
• Call Of Duty WWII                     - 12 million
• Grand Theft Auto VI                  - 32 million
• Gran Turismo Sport                   - 10 million (Assuming it's recieved well)
• Gran Turismo 7                           - 11 million

Xbox One

• Grand Theft Auto V                   - 10 million
• Grand Theft Auto VI                  - 13 million
• Some CoD assuming the franchise stays popular

Switch

• Mario Kart 8 Deluxe                  - 11 million
• Super Mario Oddysey               - 12 million
• Mario Kart 9                                - 18 million
• Pokemon Switch 1                      - 15 million
• Pokemon Switch 2                      - 14 million
  
• Smash Bros Switch                     - 10 million
• God knows what bundled game, maybe an Animal Crossing game?
  

Forgot to add that, I was actually going to.

Even if COD stays popular I don't see it sold 10 million on both console unless ppl want to double dip. HZD has a chance to sell over 10 million if it get a bundle, same story with Zelda. I'll just add another wildcard which is Splatoon 2.

Edit: Also 32 mil for GTA VI on PS4 would be insane. There's no way it would reach that number unless being massively bundled. Do we even have any single SKU break 30 million since the Wii days?

I don't think GT: Sport will do 10m+. I don't think it has as wide an appeal as the previous GT games.

If you're talking about Nintendo games I think Splatoon 2, Animal Crossing Switch, and Zelda are also definites

I don't know enough about the other guys, but I can speak about Nintendo.

The games you will probably see top 10 million will be: Zelda, Mario Kart 8, Super Mario Odessey and maybe Splatoon (thinking round 8-9 Lifetime).

As for Red Dead Redemption, the last game is planned to ship 15 million(if it hasn't already), so 10 million for the sequel is possible

"He did confirm a few things, however. Zelnick said 2010's Red Dead Redemption shipped 8.5 million copies in its first year, going on to ship 15 million in all."

Can only speak to Nintendo.

Zelda 12-13 million

Mario Odyssey 12-16 million

MK8D 15 million

Splatoon 2 10-12 million

Smash Bros 10-20 million

2d Mario 10-20 million

Pokemon 20-25 million

Animal Crossing 10 million

9 games on PS4 that we know are coming/were released:
-GTA V
-Red Dead Redemption 2
-CoD: BOIII
-Fifa 17
-Fifa 18
-Uncharted 4
-Star Wars: Battlefront II
-Spider-man
-The last of Us part II

Not sure about: Cod WW2 and Destiny 2. Call of Duty franchise is on a decline and the first Destiny had a bad critical and fan reception which can hurt the sales of the sequel.
