to the PS3 adjustments argument I would like to add a few thoughts
1. As Sony most likely lists PS3s ordered/manufactured a large number of them being transported sitting in warehouses and on store shelves is common knowledge, But there are also PS3s that are put up as prizes or otherwise given away and then there are ones that got stolen or fell off trucks were damaged in transit etc.
2. The current shortages mainly in US is probably because retailers underestimated demand during/after the holidays and didn't order enough this also explains why a lot of PS3 may have been ordered that haven't reached shelves yet (large freighters can take weeks to cross oceans) also a lot of PS3s were probably ordered for big releases like God of war 3, Final fantasy XIII etc and if there were a lot of special edition Consoles they won't go on sale until the games release.
3. as has been said most of the adjustments were made in Others that is reportedly hard to track and ioi may be using a different method to extrapolate sales or got some Annual sales data that leads them to adjust sales
or they just hate the PS3 /JK
