Which of these games will sell the most (Battle of the Titans)

[Metrium]

To help ppl make their predictions, here's the list of the 3 games predecessors total sales.

CoD:BO2: 24.57million
GTA:IV: 21.03million
Pokémon Black/White: 14.76million (did'nt put black2/white2 since they were sequels so clearly did'nt sale ''pokémon numbers'' because of that)

So Pokémon seems to be at a clear disadvantage, but I think that it will be the only one of the three that will outsell it's predesessor for many reasons...
-First, it's the first game on the console, I think like Zelda games, the first Pokémon game will sell much more, so I perdict numbers closer to Pearl/Diamond.
-The game seems to be the one adding the most, and it seems to be bringing old fans back way more than previous games (from what I'm hearing around me)
-It will have the entire 3DS lifespan to sell.

Reasons I think GTAV will not sell as much as IV:
-It's launching on dying consoles and not next gen (as far as we currently know). So it will sell alot this year, it will also have good sales next year, but unlike GTA IV, it won't be able to sell for 5 years.

Reasons I think Ghosts will not outsell Black Ops 2:
- CoD is slowly on the decline.
-The ''Ghost'' IP imo will not attract as much ppl as the already known ''Black Ops'' or ''Modern Warfare'' IPs.
-The new consoles will hurt the sales. It will obviously be impossible for the PS4/Xbone version to outsell it's predecessors. And since the game is bought by alot of ppl by peer pressure, the peer pressure will not be as strong. By that I mean, some ppl will buy it on next gen, so alot of ppl who can't buy next gen yet for many reasons will not see the point of buying the game on their current gen since they won't be able to play with their friends. So instead of having all you friends buying BO2 on xbox 360, this time you will have few of your friends that are the hardcore fans buy it on next gen, few that are also hardcorefands buying it on current gen and everyone else not sure if it's worth it buying either version just to play with your few friends still playing.

But how much will X/Y outsell Black/White and how much will GTAV and Ghost sell less than IV and BO2, that is a answer that I cannot give.

@Enrageorange Your number for GTA and Pokemon are plausible altho I'm not sure I agree with. But there is not way that Ghost sells 30mil.
