I actually have been watching amazon for quite a while. When the ps3 came back from out of stock, the xbox 360 sales declined from 15-20, to around 26-52, and the ps3 replaced the xbox 360 location. The wii is still sold out, and doesn't appear declining, at around 8-10. Psp moved up, in the few past days due to the price dropping. It was around around 38-50 and is now selling faster then ps3 at around 13-16. Not once did I notice the xbox 360 sold out, on amazon for the past 4 weeks.
thats quit interesting, because between 3-31 and 4-6 it was sold out at the american store, and in the UK and DE stores the Core version was sold out (in germany it usually sells better than the premium one) and the premium version somewhere (i dont know if its UK or DE) was as low as 20 for a few days, even after that only in the 50s. so i dont know what you saw, this is what i saw, i track it day by day.
