I don't think third parties really know what to do with Nintendo yet. For many companies, so far the (admittedly very successful) answer to the DS is often ports of older RPGs and Imagine™ shovelware titles. However, I think the overall quality of the third party lineup for DS is much stronger than the Wii's.
On that end, I think a lot of game publishers right now are flummoxed because games for the Wii really should not be anything like games for the PS3 or 360, and for the last few generations, game developers have never actually faced a situation where the experience of one console is vastly different from its competitors. Wii's biggest strength is in its controls, and if you're attempting to put a game on all three systems, you're not going to utilize that strength to the best of your abilities because that will not translate to the Playstation or Xbox version.
If you take a game and build it from concept to publishing only for the Wii and really put a lot of thought and care into how you can best utilize the waggle controls, you'll end up with a much stronger title. Boom Blox is a great example of that. Clearly, that game would have been zero fun at all if released on the 360 or PS3, but on the Wii, it's like virtual Jenga, only better.
Eventually, I think game developers will come to the point where they realize they have to completely separate their Wii and PS/360 development, and the Wii lineup will be considerably better for it.
