Well to be fair, 360 could sell as much as 150k a week better then PS3 WW. Looking at EMEAA Charts, PS3 is only sold 60k better then 360 last week (No Black Friday in Europe), and it sold 30k better then 360 in Japan. This week 360 sold 230k better then PS3 in Americas, so I think it's very possible that 360 could outsell PS3 on 3/4 upcoming weeks by 100-150k.

Final Fantasy XIII-2 week in Japan, we will probably see a smaller margin lead for 360, maybe 50-100k.

Adding all those numbers together, that means 360 could close the gap by as much as 350-550k, making the annual gap between 450-650k in favor os PS3.

For the week directly after christmas, anything can happen. Last year the difference was in favor of PS3 by 100k, but there were 360 shortages as early as the week before christmas. If MS can supply demand, 360 could outsell PS3 for that week.

In Fact, before VGC was aware of the shortages, they had 360 estimated to sell just under 100k more units then PS3 that week. Data was adjusted later.

Regardless, a 400-800k gap is likely, and basically exactly what I predicted, and not much off from you.

Let's see if MS can prove us wrong.

The answer to your question is in your quote.  It's in the bolded section above the numbers.

Thanks to great sales, as well as adjustments to previous weeks, the 360 has been able to drop the gap by another ~185K for this week. However, the gap needed to be dropped by ~249K, so now the 360 must outsell the PS3 by ~271K for the next 3 weeks if it hopes to at least tie with the PS3 for the year WW.

As of week ending Dec 3rd - 11,196,131(PS3) - 10,383,951(360) = 812,180 or ~271K over the PS3 for the next 3 weeks.

With 4 weeks of data left to go, the 360 needs to do (on average) ~203K more per week.

Seeing how I expect the 360 to outsell the PS3 by 300-400K for the weeks ending 17th & 24th, I'm pretty damn confident that the 360 will take it.

Again, the PS3 is almost 100% guaranteed to outsell the 360 by AT LEAST 80K for the last week of data.  There will be a sharp decrease in 360 sales after Christmas in the US, as well as Japan holiday boosts for the PS3 continuing into the next year.  This has happened the last 2 years, as well as in '07, and it will happen again this year.  In other words, you need to estimate like there is only 3 weeks worth of data for the 360 to catch up, not 4.  Also, with NPD numbers in, it looks like the PS3 was undertracked in the US for the month of Nov by ~160K.  So, there will be further adjustments next week in the PS3's favor.

I think what some fail to acknowledge is how big the PS3 is outside of the US and UK.  The PS3 is going to be seeing much larger boosts in EMEAA and Japan compared to the 360, which is going to decrease the gap the 360 (even with incredible US sales) has over it on a weekly base to ~100K-200K.

I think that X360 will fall short of 400k in shipments.

Sorry meintiel, your notion that the 360 has no chance of outselling the PS3 that week doesn't float for me, frankly I find it absolutely ridiculous.

I will discuss no further in this thread untill numbers for 10th & 17th Dec. are in.

What's the GAP difference now. I know there was some adjustments. Someone said it was around 750K with 3 weeks to go, We still need Dec 11, 18 and 25. I expect week of DEc 25 to be close to 2 million.

Pretty much this, ppl focus too much on USA/UK sales to make these predictions and forget that the PS3 has a hughe lead on the rest of the world, also completly discreditting the FF XIII-2 boost like most ppl are doing is ridiculous, that game will give the PS3 something around a 60k boost in Japan and thats pretty significant.

Also if vgchartz dont adjust the PS3 up based on the NPD numbers the site is in denial.

LOL, they might not be able to meet demand, but I doubt it. It's not like there is a completly new X-Box console out like last year. I don't think this will happen.
