What are the different game systems?

I think that it will be the 3ds since it will have better graphics than the dsi. It will also show stuff in 3d. It also takes photos but not in 2d but in 3d! Also the 3ds will have a gyroscope sensing how many steps you take (like a poke-walker). Mii center allowing you to take a picture of somebody and make it into a mii. But that's just the system;the games (3d games) allow you to see the depth of an object making it easier to play a game. The games are Paper Mario, Mario Kart, Star Wars The Clone Wars III, Tom Clancy's Splinter Cell, Super Street Fighter IV, Monkey Ball, etc...
