I completely forgot about FIFA. I actually quite like certain sports games myself, but I don't for the life of me understand people who run out and buy them every year. So little changes in most cases. I personally usually stick to picking them up on a bianual basis, and even then it's sometimes not a very noteworthy upgrade.

Hes wrong, Black Ops 3 on PS4 already sold 15 Million, with Xbox over 22 Million and with last gen 26 Million !!! Infinite Warfare is another Story, but i think if World War 2 ends up being a good Cod game again, it could sell like Black Ops 3

Since Fifa 14 I buy every Fifa and enjoy them every year again! And for Fifa 18 on PS4 i actually expect it to sell like 13-14 Million, because of a bigger Userbase, Sony having marketing/Bundle rights now, Legends/Icons being available for the first time ever for PS4 (and PC) Players and the World Cup Mode for Ultimate Team will return this/next year, so anything less at least on PS4 i would see a bit disappointing.

Besides Fifa, Star Wars Battlefront 2, Destiny 2 and Cod World War 2 will the 4 biggest Multiplatform games of the year and in terms of exclusives i think Zelda and Mario Kart will sell the most. GT Sport will be a longtime seller for years and it will launch to late to make a big enough impact and yeah sadly we dont know how it will turn out after the last few games. For me its the most anticipated Game of the year, but that doesnt mean it will end up in the sales of GT 1-5 and the majority will buy/enjoy it, but i really really hope it does !!^^

I'm not wrong at all. This is about best selling game of the year.

FIFA 17 sold ~15m in 2016
CoD IW sold ~10.3m in 2016
CoD BlOps3 sold ~16.3m in 2015 (without 360 and PS3 sales, as CoD WW won't launch on those systems)

Thus FIFA 18 will sell around 15m in 2017 and CoD WW probably between 10.3m and 16.3m in 2017, maybe even higher.

Okay i misunderstood you then, sry.^^

This.

GTS will sell 10m plus in 2.5 months!? Not gonna happen.

CoD or battlefront

1. COD
2. Fifa
3. Destiny 2
4. SWBF2
5. AC
6. GTS

Without those 5 multiplat juggernauts yeah. I do think GTS will beat AC in the long run to ~10M. GTS will be a yuuge service game and it'll be continuously updated in the coming years, like it'll be a new game. GT5 and 6 got new intros and disc releases but this will go beyond that.

I think Mario kart will overtake zelda by the end of the year, making it the best selling exclusive. 

-EDIT-

Actually if we include the wiiu version of zelda, then yes zelda comes out on top. 

In my case I get them every two years (Fifa 14 and 16 until now, will get 18 now), and most people I know do it that way at least
