That's my troughts about this IDC numbers.
- 360 numbers are accurate... a little less or more but that's what I thing Microsoft shipped this quarter... ~6 million.
- PS3 numbers are odd... I think they shipped 7 million or more this quarter... so all dependes how much PS3 shipped at the end of September... we know it shipped 70 million in 4th November... so for 31th September I will assume 68.5 million shipped (for the best scenario)... so using this number we have:
+ 7.0 million shipped: 75.5 million
+ 7.5 million shipped: 76.0 million
+ 8.0 million shipped: 76.5 million
I think harder the 8 million shipped but the 7 million is probable... so the IDC can assume the Sony will ship 8 or a little more million this quarter putting the sales at 66.5 million... so they rounded to 77 million.
Is it prossible? Yes.
Do you think that happened? No. I will be surprised... I think Sony shipped 7 million PS3 this quarter... and my estimate for 31st Sep sales is in the best case scenario... so it can be lower.
