I wouldn't be so sure.  Halo bundle is ahead on monthlies right now but won't be by the end unless something changes.  And it's the only one in the top 50.  The PS4 has 3 in the top 50 that count towards this month:  TLOUR, Destiny, and NDC.   Given the August preorders weren't that awesome it seems and September was bad, I think PS4 will win fairly comfortably. Not a slaughter by any means.  But definitely way off what everyone was expecting and not at all what MS was probably planning.

We shouldn't just look at the top 2

Halo bundle ahead only by 2 spot to NDC bundle. October will be close but even if XB1 win october by 50k-100k i think it will be still consider a PS4 win by some people. But i'm still leaning towards a PS4 win going by my observation on this thread, either way it will be close.

I agree with SWORDF1SH. Don't look at Halo and NDC at all (too close). Look at the rest for this month : TLOU #38 and Destiny #46 for PS4, Gears #99 for Xbox One. If Halo 5 pre-orders were not at least in the top 50 (even 40 IMO, minimum) in August, it's obvious that the PS4 win the october Amazon chart easily (and don't forget that october's sales are way higher than august's sales, so a #40 in August would likely not match a #40 in October). 

That's all really. If we trust Amazon charts again, PS4 wins quite easily this month (IF). 

Wow, the NDC bundle is a lot closer to the Halo bundle than I thought it would be.

I think if the X1 wants to get back the US, it needs this holiday. It will be next year when the PS4 price cut will shine and will increase the gap during the "pre-season".

And we can be pretty certain there will be a remodel and further $50 price cut for PS4 around this time next year. With talk of PS4 possiblky doing a pulling New 3DS it could be that a new and improved PS4 will slot in at $399 to up-spec and be relatively on par with NX and the lower spec'd PS4 comes in at $299, or maybe even $250 depending on whether SOny wants to run with 2 grades of PS4 long term or if they just want to clear out the lower spec'd version and only sell the NPS4. I just hope they don;t fragment the PS4 market doing that. I want all games to run on any PS4, it's just the graphics / re / fps settings that get lowered if you have an early gen spec'd PS4. I'm not interested in re-buying PS4.

In terms of what MS does with Xb one I think they need to decide what the wider MS senior execs and board of directors need to see from Xb one in order to allow MS to stayin the console game. Do they need to see Xbox making a profit, or do they need to see Xbox managing to achieve a decent install base AND  strongly compete for number 1 position in the USA? If profitability for Xb one will ensure a 4th Xbox then I don't think dropping Xb one below break even for another year is going to fly. If install base is key, and profitabiloty can be pushed back to late gen and next gen then I think we'll see some strong measures taken to boost Xb one sales this holiday. If Halo 5 doesn't give Xb one a strong win for October NPD then I think there will be some furrowed brows. I can imagine assurances being given that Halo 5 is the magic bullet fo Xb one in the USA and that once Halo 5 hits the real turnaround in fortunes for Xb one in  North America would happen. 

The mistake in thinking with Halo though is that Halo's player based did not increase in the 7th gen in the USA in-line with the increased install base. Xbox 360 install base nearly quadrupled (probably tripled after taking RRoD into account) but Halo only increased by 20% or so. That means Halo was never going to be a magic bullet for Xb one in the USA because 80% of the Halo player base is contained within the 15.7 million people in North America who bought the original Xbox. MS must be aiming for a minimum 20 million in sales for North America, which means something other than Halo needs to drive those sales past the 15 million mark.

I agree with that and it looks like NDC might overtake it in the final update if things doesn't change. With 3 PS4 bundle in the top 50 and 1 bundle ahead of Halo bundle, PS4 will win october, maybe not by large margin but it will still be a big win for Sony.

We will probably see the PS4 slim for $300 next year. We will probably also see an Xbox One slim for $300 also but that just means the PS4 will continue to beat the X1. I can't see a more powerful model being put out though. Maybe a slight upgrade to improve loading speeds and UI responsiveness etc, but nothing that will improve games.

With the Halo and Uncharted bundle being so close and the Uncharted bundle outselling the Halo bundle in the hourlies I wonder if it can overtake the Halo bundle on the monthly charts soon. But based on the monthly charts I'm going with a PS4 win. The Uncharted and Halo bundles are almost even with Uncharted gaining ground every hour, and then you have the Destiny and TLoU bundles absolutely beasting the GoW bundle.
