No idea, several of them will do quite well though.

Far cry or sf5 should be the safe bet but who knows

I imagine Far Cry and Street Fighter will sell the most...no idea between them though. I'd be happy if Fire Emblem beat one of them...but I'm not gonna hold my breath.

If Fire Emblem can't beat Nardo I'll probably go sit in my room with the lights off.

SFV easy

Fates would have won if it had a complete worldwide release, not just for NA. As it is, probably SFV will get the crown this month. Far Cry Flinstones will underperform at release, the concept is too weird for a Far Cry game, and I don't see that much hype around it (it will sell millions, of course, but it will underperform in Ubisoft's eyes).

Imho the lack of Shooting will be a big problem for the FCP sales, I expect the winner to be Either SFV or FE: Fates, for the latter, people should keep in mind that there are 2 versions of the game so probably many people will buy both !
I won't even take into consideration Naruto...

Even if they lose, I bet it'll be a lot closer than you think! 

/thread.

Very likely that is going to be the result.

(street fighter could edge out FCP, by a tiny amount though)

If the Far Cry would be mainline, i think it could take the month easily.

IMO Primal doesnt have much appeal, so i say that Street Fighter 5 will top the month.

Well of that order it be amazing considering Naruto shipments are over 500k. I don't think it'll do under 350k sold
