Here's some new info on the DSi for those that are interested. I did a bit of digging and found that the DSi is more of an upgrade than simply a camera and a torn out GBA slot. From the wiki:

Apparently it's going to have a slightly better processor, and 4 times the amount of RAM. It also adds 256MB flash memory, which is not much. The screens are slightly bigger, it's thinner overall, and the battery life has been somewhat shortened due to the new features. I'm still going to wait to see how it works out, but it's nice to know that it's more of an upgrade than I initially thought.
