Megapixels vs. FPS

We're finally upgrading our Nikon D70.

Considering that 90% of the pictures we take are of our kids playing sports (tennis, basketball, soccer and baseball), which camera would you recommend - Nikon D7000 or the Nikon D300s?

The former boasts 16.2 megapixels and 6fps while the latter takes 12.3 megapixel pictures and shoots up to 7-8 fps.

Should I go for the higher picture quality or the higher frame rates? Please keep in mind that our budget is under $1,600 for the camera body, and - like the D70 - we'll probably have the camera for a very long time so we want to "future-proof" this as much as possible.

Thanks in advance for your advice.

 

First of all, I wouldn't say the D7000 has higher picture quality than the D300s. The D300s is Nikon's pro-level DX camera. The newer D7000 is a high end consumer grade camera. It has a newer, increased resolution sensor that has been the subject of much controvery in the Nikon community. The D300s, however, is a model that will be replaced in 2011 (unless earthquake damage causes that to be postponed). If you want the camera to be "current" for a few years, you may want the D7000 or wait for the D400 release.
