The reason the DS numbers are so low is because there's a shortage WORLDWIDE! The DS is doing so well in North America, Europe and of course Japan, Nintendo is having a hard time getting enough units out to all three regions fast enough to meet demand.
Also here's something interesting to look at, here's the NPD software total for the Wii and PS3 for people to compare.

As anyone can see, the Wii is owning the PS3 hard in both hardware and software. And when you take into account it cost third parties MUCH less to develop for the Wii and alot of their games sold just as good or even better on the Wii, third parties should be very happy with their Wii sales.
Any third party that decides to give more support to the PS3 over the Wii after this is a complete moron.
