The eagerly awaited upgraded to the Nintendo DS Lite will be making it to the U.S. on April 4th, 2009. The Nintendo DSi is a major improvement over the DS lite. The new model includes 2 cameras, larger screens (top and bottom), and an SD slot instead of the game boy cartridge slot. The SD flash storage is going to work with the new DSi Shop, an online gaming marketplace. See more pictures of the Nintendo DSi after the break.
