As you may already know, a new version of the Nintendo Ds, the Dsi, will be released in November 2008 in Japan and in 2009 for the rest of the world. Even though the gameplay will be quite the same, the new DSi will have his advantages and inconveniences.
Here's the Japanese trailer (sorry, I didn't find the one in english)
Major advantages :
The new engine will contain two 0.3 mega pixel cameras : one pointed towards the user and one on the outside of the shell.
