When will the PS3 pass the 360 in monthly sales in the USA?

[libellule]

Obvioulsy, not in 2007,

Possibly in 2008 (during some special momentum big games+price drop)

what people forget about momentum is that PS3 has increased her sales by 2 with her 100$ price without any games.
And after 1 month, the factor "2" is still here...
