The screen is 90 percent bigger, with larger bottom and top screens. It's called the Nintendo 3DS LL in Japan and the Nintendo 3DS XL in the West. The top screen measures at 4.88 inches and is 90 percent bigger, while the bottom screen is 4.18 inches and is also 90 percent bigger. For the 3DS LL, the battery will last 3.5 to 6.5 hours while playing 3DS games (as compared to 3 to 5 hours with the 3DS). The battery will last 6 to 10 hours for DS games (as compared to 5 to 8 hours for the 3DS). To cut costs, Nintendo is selling the AC adapter as a stand alone in Japan, but the 3DS LL will work with current 3DS/DSi/DSi LL plugs. Nintendo is packaging the 3DS LL with a 4GB SD card.
