It seems that the differences aren't so...black and white. The first screens of the upcoming 5th Generation Pokemon DS games have surfaced from Coro Coro magazine (via Serebii.net). Although the upcoming games look extremely similar to the already existing Pokemon games, (Read: vibrant colors) we can see some hints of a fully integrated 3D perspective in the screens. Aside from that there are glimpses of the new battle scenes, two images of a large city, and what appears to be a new combined Pokemon Center and Pokemart. You can browse them all just down below.
