I think he's saying that the PS3's year-over-year sales are up. And on a large-scale basis, this is more or less true: for most of 2007, the PS3 was managing between 250,000 a month and 500,000 a month (excluding oddities and holiday months). This year, it's averaging between 650,000 and 800,000 (again excluding oddities and holiday months). That's a fairly good jump, around 400,000 units a month more worldwide in fact.
Comparatively, the 360's 2007 range was about 275,000 to 550,000, and its 2008 range is about 500,000 to 700,000, a jump of only about 250,000 a month at best. The Wii, however, has gone from 850,000 to 1,100,000 a month average in 2007 to 1,250,000 to 1,500,000 a month average in 2008. Again, a solid 400,000 a month jump.
So there is some grounds to say that the PS3 is in fact picking up steam as fast as the Wii. However, it should be noted that this means that it's only managing to not be left completely in the dust by doing this; it isn't catching up with the Wii at all, or even closing the gap of per-month sales between the two systems. Picture it as a rapidly-widening chasm that the PS3 is trying desperately to pull back together, and is only managing to keep the chasm from widening any faster than it already is, and you have a pretty good idea of what's going on.
