That sounds like it could probably be one thing. It would be cool if they found an interesting use for the SD slot, but I think it will all be related to the camera instead.
Off-topic: I kept seeing these interracial dating advertisements on here, and I wondered why the heck they were on this site of all the places. Then I realized it's because of the term "Black and White" showing up so much lately. lol
Hmm, is the DSi more 'enhanced' graphic wised than the DS Lite/DS? Like can it handle greater graphics with smaller space?
response to your off-topic: they have the weirdest ads on here...I saw a few for gay interracial dating a few days back :D.
