Because everyone is going to rush out to buy a console for a game they already own on their 360s obviously. 

My prediction, they will loose every single month until maybe a $100 price hits or maybe Halo 5 releases.

You shouldn't look forward to a battle that you're going to lose, no matter how badly you lost the last one.

The Master Chief Collection and Sunset Overdrive will not outsell LittleBigPlanet 3 and Drive Club by a very wide margin, therefore exclusive content will not make a major difference. Additionally, the PS4 has all of the momentum as well as superior multiplatform titles so the best Microsoft can hope for is to sell enough hardware to at least remain relevant in 2015.

The XboxOne won't outsell the Wii U in November even in the United states. I think this is garunteed if Nintendo releases a smash bundle like the Mario Kart bundle. It would be $330 come with the game the game cube smash controller and  the adapter also register smash bros on club nintendo for a free game. This is of course speculation if they don't do this I have no idea what will happen and we won't know about it untill October because the Mario Kart bundle was anounced about a month before it came out. I am confident of this because I have many friends who realy like Halo and xbox but they would easily pass up on a remake colection to play the new smash bros if Nintendo realeses a deal that good. Of course that is only acedotal evidence, but considering how well the Mario Kart bundle did why shouldn't Nintendo do the same with Smash bros just make more of the bundle so they don't sell out.   

He may have a point. Whether it's U.S. or worldwide.

PS4 has September won. October is where things will start to get interesting.

what? CoD bundle and hopefully Halo MCC bundle  alone will obliterate Wii U sales. 

I have plenty of friends waiting for the MCC. 

I think you are forgetting about a little game...maybe you have heard of it...Super Smash Bros.?  I think you are in for a rude awakening when you see what that title does for WiiU sales....COD is multiplatform, and is more than likely going to look and play better on the PS4...the overprice 1TB bundle isn't going to move as much hardware as people think...especially when you can upgrade the PS4 to 1TB for around the same price.  The timed DLC isn't going to be as huge of a deal as it was last gen, either.

well it better move more consoles than MK8 did. 

and both Wii U and ps4 will individually beat xone in those months.

It will be a cumulative effect more people will buy Mario Kart 8 during black Friday because there will be deals for Mario Kart 8 and the other Wii U skus for those that don’t want smash bros. The best thing Nintendo could do is release dlc during November for Mario Kart 8 and run more commercials for it and they could also patch it to use the game cube controllers. A smash bundle like I described will look pretty good next to the 100$ smash controller bundle for those who don’t own a Wii U.
