If esports comes to ps4 (mlg) then it's pretty much all in sony's ballpark. Also the fact ms fans have halo, sony can capitalise on that. Make a cool new bundle and you're sorted sony

If MS creates a bundle with the elite controller, it will sell more on X1, otherwise PS4.

if the marketing deal include bundle, I will go with ps4, otherwise xb1.

Sorry but if Sony have the marketship leader, that's not mean PS4 + Black Ops III bundle is very likely?
Idk...

MS can't do a bundle this year because of the Sony marketing deal, but they might do their 'any free game' workaround.

I think MS will still win, just barely though.

Exactly, they could still include COD and Battlefront with an elite controller for 499$, even though that might loose them cash :).

I think the PS4 version will sell more with all the marketing stuff...

Well the ps4 does not have any meaningfull exclusive game coming in 2015 that will help push cod sales on their console,besides xbox has halo 5 so im pretty sure ps4 will take this one.

Since the PS4 version is pretty much neck in neck, and at times even sold better than the XB1 version....I say PS4 due to the marketing deal plus early future DLC.
