On Paper MS should win November, 50$ pricecut / Sunset overdrive / HCC / advertise for CoD & Assassins Creed.
On the other hand we have Sony who has yet to annouce anything, also the PS4 is not to be estimated. PS4 word of mouth has seem to have gotten stronger lately.
It is anyone's game.
But if MS can not win November, then they will not win December.
