As the guys mentioned: Adjustments.
Please do not think this is trolling or anything like it, but I think VGC does not know exactly where Sony sold (shipped) those PS3s to explain the gap. We do get pretty good data for NA, Japan and sometimes for UK, so it seems like they just put it in EMEAA. I doubt VGC knows where exactly. But that should not discredit the great work VGC did with the tracking in the past years.
The truth is , for those who still trying to question vgchartz numbers or Sony's shipping numbers, Nintendo's 3rd quater report showed that the PS3 was selling way better than we had it here, and that's just regular Europe. In Fact, after the Slim came out, the 360 only led for a couple weeks before the PS3 went right back ahead.
Ok, 360 was outsold by the PS3
but WHY the bump at the move release ?
You guys really should look at past history before saying all this junk. In the last 2 weeks, PS3 is only 5.25% ahead of the same week last year. It always goes up early like this in Others this time of year, likely for early Christmas purposes.
