My understanding is certain high-powered clients get a preview of NPD data a day before the 'full public release', which means this is likely based on final or near final NPD data. Still, I imagine it won't be much of a victory, as every source I have seen, whether Pachter, VGC, Sim Exchange, suggest a near tie between 360 & PS3.
I'm expecting something like this
Wii-DS-PS3-PS2-PSP-360
Wii will be 300k-500k (i'd guess 420k)
DS will be 280k-380k (i'd guess 330k)
PS3 will be 240k-340k (i'd guess 260k)
PS2 will be 200k-280k (i'd guess 248k)
PSP will be 220k-260k (i'd guess 236k)
Xbox 360 will be 190k-270k (i'd guess 228k)
