All of the Xbox bundles release 7 days before the games release to allow people to pre-load with the digital copy, Gears,Forza,Halo Madden and Fifa all 1 week before the games release

Woops! My bad. In that case, maybe will be 30-35 % of the total XBO sales, so, 120k-140k Halo bundle with 400k XBO. Well, of course is just my guess...

xbox one should have a very solid h2 2015
last year they sold nearly 3.3 (~3.280k) million units. this year should be between 3.5 and 4 million or even some more

XBO has sold 2.7 million October to December in the US. To be honest, i don't know if will sell again those numbers... it will be up YOY for October for sure, but November and December of last year was insanity for how usually XBO is selling... i don't think will happen again. XBO will be down for Nov and Dec of this year.

And of course not even PS4 will sell those numbers, it will sell better than last year ( 1.9 million) but not at the XBO level of 2014.

Unless it gets a pricecut.

Not gonna happen, and you know this.

Probably not, but it would've done insane numbers if it did.

you don't belive in the power of master chief (and her little sister lara)? + the new 1tb sku? :P
xb1 won't be significantly up in november and december. i dont believe that either.
but i see them to keep up with last year numbers. so ~1.3 million each month

last year october the xb1 sold only 170k units.
this year could be ~250k more alone. july and august should be healthy up, too.
september should be also up by a small margin

if the xb1 won't sell over 3.5 million, i eat a crow :D
but sony will be a deciding factor, too. if they cut the price and fight for the "cheap console for my kids christmas shopper audience", i can see this predicion fail.
if not, im 100% certain

Always makes me laugh when people are 100% sure Sony won't cut the price some time this year.

The mistake is that you don't only should see the line up of this year, but even of LAST year... Now, if we see the line up of this year, Halo is seriusly the only megaton of XBO... and will be huge, ok, but the rest... i mean... Tomb Raider can sell decent, but for decent i mean DECENT. is not a sistem seller.

Last year XBO got CoD AW and AC unity.

Unity has sold not much, but the point is that the bundle was insane. 320$ + 3 games during Black Friday!!! Call of Duty Advanced Warfare was even a important note of the massive XBO sales, it sold nearly 1.5 million only on the XBO. Black Ops III, first, will sell less than AW, all version combined, and that's nearly inevitable, COD is in decline since MW3, that's why even BO III is going to sell less, and second, now is PS4 exclusives marketing... Also, don't forget the white XBO that help a lot.

Here my estimate of XBO sales in 2014. ( October and November)

That's only my guess, but seem about right or really close, how you can see, the XBO has sold 168k in the intere month of October, and 75k the last week ( confirmed by Phil Spencer: XBO beat PS4 the last week of October, and the PS4 sold 297k that month, nearly double).

I believe the sales for this year will be some like:

31 October: 200,000 ( Halo 5 week )

7 Nov: 175,000 ( Black Ops III )
14 Nov: 180,000 ( Fallout 4, Tomb Raider)
21 Nov: 180,000 ( Battlefront )
28 Nov: 600,000 (Black Friday)

November: 1,135,000

I want say 1.15 million XBO sold in November. ( down by 90k compared to Nov 2014, 1.24m )

I also believe that XBO will be down for September. Last year was Destiny, this year is nothing, because MGS V is nothing on XBO, and Forza / Fifa sell good in Europe, not in the US. The rest ( Oct, Aug, Jul) will be up.
