Pakidan called this to my attention in Fishy's thread about milestones here:

The Wii is once again tracking above the PS3 when comparing Wii American sales to PS3 worldwide. This is the 4th time it has done this including the original launch period, then for a short time before PS3 launched in Europe, and again for a few months in late Summer and Autumn 2007 until the PS3 picked up in November with the price cut and 40GB.
And now, with this last week of data in with Wii at 521k in the Americas, and PS3 at 350k worldwide, the Wii has passed the PS3 and is 100k ahead.
