I don't see a 25,000 unit lead per week as being very significant. That's around 1 million in the months outside of the holiday season. All it will take are a few heavy hitting Christmas deals and Xbox 360 can easily win that million back.
Now if PS3 were selling 250-400K per week, that would be significant. At the current rate, it will take years to pass; and that is too late to matter.
I describe myself as a little dose of toxic masculinity.
