It's a DS successor, not a DS. Just like from GBA to DS, this is from DS to 3DS(tentative name). It won't be a DS. Why don't people get that? It's a new handheld. Going from 133mhz power to roughly 500mhz power wouldn't make it another of the same. It will have backwards compatibility for playing DS games, but it's not a DS because of the 4-5 times stronger machine, higher resolution, and 3D effects. It might have 2 screens that are extremely close together, but it won't make it a DS. Unless Nintendo calls it something along the lines of having the "DS" in the name, it's not another DS.

And oooo. Take a look. I'm not the fan of the top screen being larger than the bottom screen. I think they should both either be widescreen or both the same in any aspect, but not different aspect for each.
