This is absurd. I will be very surprised if the PS3 outsells 360 in North America for any single month in 2007. Nothing Sony could do can change that, only a monumental screwup by Microsoft. (E.g. trying to keep the current price juuuuust for one more month over and over again.)
Actually, if PS3 doesnt outsell the X360 in any single month in 2007 (aspecially Nov07 and Dec 07), the PS3 is doomed in the US. Because that would mean that the PS3 demand is far from good enough at its current price, and even thought there will be price drops, there is no way in hell Sony can do a price war vs Microsoft and their endless supply of cash.
