Really late to this thread, but better late than never. Just wanted to make an observation regarding VGC estimates.
According to my estimates from this thread, at the end of their last fiscal year, Sony had shipped 77.4M-77.7M PS3s. This was also the last fiscal year where they started to include PS2 numbers with their PS3 numbers, so we know the PS3 has, in fact, shipped 3.1M in the last two quarters. So, at the end of Sept, Sony has most likely shipped 80.5M-80.8M units. VGC shows 79.8M units sold to customers, or 700K-1M still on shelves.
Seems to me that VGC tracking is either pretty spot on up until now or just a smidge undertracked. Either way, I'm not complaining.
