Since the DSi has a faster processor & more RAM, DSi games won't be playable on the DS. However, the DS is a huge market, so I suspect developers will continue to release DS games (which will be playable on the DSi) for some time. In fact, I bet developers (other than Nintendo, who want those upgrade sales) won't create DSi games unless they are using the camera or the SD slot or are forced to by Nintendo.

 

It may even be possible to make dual format games which will provide more advanced features on the DSi, although I doubt many developers outside of Nintendo themselves will bother.

Of course, anything downloaded from DSiWare is DSi only.

 

Companies might release DS+DSi dual format WiFi Connect games so they can use WPA on a DSi and WEP on a DS.
