When will PS3 overtake 360 in other's overall sales?

[Non Sequor]

The gap is currently 2.4m. Last week the PS3 outsold the 360 by 100k. Maintaining this rate, it should take 6 months for the PS3 to close the gap.

However, it's unreasonable to expect the PS3 to continue to outsell the 360 by 100k per week. 50k per week might be doable, but if the 360 gets a price cut this spring, I'm not sure if the PS3 will be able to close the gap this year.
