I think it's really early for a new DS. I mean the DSi just came out in April and they're already going to bring out another one? I upgraded to the DSi and I'm sure when the new one comes out (if it's worth it) I'll want to upgrade again. Unfortunately my husband will kill me (or divorce me) for it.
After all I bought the DSi when it first came out in April and then when they announced the pink and white ones I sold my blue one to get the pink one. He won't be happy if I upgrade to the new one.
