Halo Reach will only push a lot of 360's in America and Kinect won't have much effect in my opinion. As I see it most "Gamers" don't like Motion controls and the "Casual" crowd will buy the cheapest thing out their that has Motion controls and as of now that is the Wii. The Wii is still $100 cheaper than the 360 with Kinect and the Wii comes with 2 games and Motion Plus while the 360 comes with 1 game and Kinnect for $100 more. Also the Wii has been labeled as the family friendly console and parents will buy their kids a Wii over a 360 due to price and that family image. The 360 has already been labeled as the "Hard Core" console that has many shooters with blood and killing and Kinect(I.M.O) won't change that.

To answer the question the 360 will sell remarkably better this year over last year but I still don't see it passing the 50Million mark in 2010. The 360 should pass 50 Million as early as January 2011 though.

Let's try to be a bit analytical:

2009 PS3 slim/$100 pricecut year WE 6 Sept - WE 2Jan '10

2008 360 $100 price cut year WE 7 Sept - WE 3 Jan '09

360 is currently sitting on 42.712M as at WE 28 Aug. So to make it to 50M by year end it needs to sell 7.288M units over the same timeframe I've shown above(I'm assuming we are talking VGC sold numbers).

This means 360 needs to sell 736K units more than it did over the same timeframe in 2008. Is that likely? I'm pretty sure most people are thinking that relative to Sept-Dec 2008 360 is going to fall behind in WoW sales, or at least be more or less dead even. I think it would be a bold move to predict 360 Sept-Dec 2010 will outsell 360 Sept-Dec 2008 by nearly 750K units.

Therefore I predict 360 won't make it to 50 million on VGC by end of 2010. And unlike the almost trollish comment from Jadedx it's got nothing to do with any PS3 related material in my sig (of which there is none at the moment).

I think, at best, it will match 2008 sales from here on, so that will make it 49.264M units sold to retail if it performs outstandingly well. That's pretty much inside VGC's LTD margin for error, so you could claim that if it gets over 49M by year end then statistically it's possible that the ture WW LTD sales is at or slightly above 50M.

I think  probably will reach 48-49 Mil, but it will shipped > 50 Mil

but i could be wrong, and somehow with reach fable and Kinect it will boost sales.

September-October maybe 2 Mil

NovemBer 1.5 Mil

December 3.5 Mil

no it will miss it but by very less near 48.5-49m

I think the xbox360 will reach 50million easy maybe as high as 52million

At the moment the xbox360 has shipped 41.7million consoles so it needs to ship 8.3million in 6 months.

Last year it shipped 7.3million in the 6 months of 2009, so close.

This year though it has 3 extra things, in order of importance

1. slim/pricecut

2. kinect

3. halo reach

They will ship from 8.5-12million consoles

Ship 12 million within the space of 4 months? >1 year's retail sales? That's a bold prediction.

the 360 will break records this december selling 4 million npd alone selling more than the wii did last year

depends on kinect and reach

You have misread what I wrote, I said from 8.5 - 12 million in 6 months.

It shipped 7.3 last year. Now you admit july and august and september so far its being doing better than 2009 it will easily sip more than 7.3 this year, probably around 10million.

A bold prediction is the poster after you. 4 million in december NPD, which is just pure fantasy. I notice that poster didnt except my bet about GT5 selling more than 10million

It will be close but I don't think so.  I'm thinking right around 48 million, which is still VERY VERY good considering this isn't even the end of the generation and if you told someone last gen that the 360 would sell over 50 million consoles in its lifetime people would have called you insane.

However if Kinect takes off BIG in America it just might push it over 50 million.  Kinect will have a bigger impact than Move but I'm not convinced it will be able to push hardware like the motion controls did for the Wii.  Only time will tell though, the holidays are always fun
