I'm probably not getting it right away, but I'm interested for the larger displays and the shiny design. I only have a DS Lite so that would be an upgrade for me.
To those complaining it was too quick an upgrade, if you bought the DSi I'm not really sure it's an upgrade. It's a size variation, kind of like the color variations. You can always trade in your current model, which isn't that old and get a good discount.
Otherwise you need to stop complaining because frankly you don't need to buy it, and a whole year for a handheld device is not a short time at all, you're overreacting on that one.
