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.
you are absolutely correct
the shipped figures were very different as VGC didn't track it
they put the figures around MOVE's release as an assumption it caused the spike
but the didn't track it
plus the shipped vs VGC gap was even there at before last quarter
so it wasn't MOVE bump as allocated by VGC
VGC just didn't track in those areas
