Nintendo has unveiled a new model of its DSi handheld console, which will appear as the "DSi LL" in Japan, or "DSi XL" in Europe. As you've probably already guessed, the DSi XL brings larger 4.2" dual screens. That is about an inch more than the current DSi's 3.25" displays or the DS Lite's 3" screens.

The DSi XL will be packaged with a regular stylus, in addition to a longer, thicker pen-like stylus. It is reported that battery life will be about four to five hours on maximum brightness and 13 to 17 hours on minimum, which is on par with the DS Lite. Charge time is around 3 hours when fully depleted.

The latest DSi will measure 161mm wide x 91.4mm long x 21.2mm thick, and the new stylus will measure 129.3mm long. It will feature an SD memory card slot, a stereo headphone/microphone connected terminal, and will be available in red, brown, and white.

The DSi LL will hit Japanese store shelves on November 21 for 20,000 yen (around $220), and the DSi XL will arrive in Europe sometime in the first quarter of 2010. No details have been provided for a North American launch.

Update: Kotaku is reporting an early first-quarter debut for North America as well.
