Predict end of gen sales for each console and handheld - PREDICT WHILE YOU CAN, THREAD WILL BE REVIVED WHEN GEN IS OVER!

[Sirius87]

Wii 108M
PS3 106M (Bluray will help selling the console when PS3 starts to cost ~100 $)
XBox 360 91M (imho Microsoft will discontinue XBox 360 2-3 years after the release of its successor)

No idea about handhelds.
