Across all platforms and lifetime, battlefront easy

vs ps4 battlefront, halo easy

per platform Halo easily wins. total sales though it will come down to game quality at release, either could take the title, only takes buggy/broken multiplayer at release to doom either title to mediocre sales.

Halo, Battlefront and Halo

I think Halo will move about six million on Xbox One in its first year. About nine million when all is said and done.

The rest, I don't know how they traditionally perform.

EA wants Battlefont to sell 10 million copies this fiscal year.

Battlefront is launching to an audience of probably 40+ million consoles alone, and PC sales. Halo is launching to an audience of probably 16. Battlefront is just more likely to sell more because it's on 3 platforms as opposed to one.

battlefront ps4 vs halo, I'd say is a toss up, but it favors the ps4. There's going to be a lot more ps4s, meaning a lot more potential customers. There's the idea, that halo is the reason to get an xbox, but the sales don't really reflect that. A lot of people will buy it, but not as much as some might think based on past history. I could be completely wrong though. 

Battlefront overall vs halo overall. It's almost definitely battlefront unless it completely flops, or halo exceeds sales expectations by a mile. 

Halo vs battlefront xbox one. Almost definitely halo. 

Battlefront will sell more across both platforms than Halo will, but Halo will sell the most on an individual platform.

Don't underestimate the power of the dark side.

Lifetime, Halo 5 in every category.

This year's grand total, Battlefront.

Then, unless Halo manages the biggest attach rate, ever, it's not going to overcome this odds.
