September 13th marked the 25th anniversary of Super Mario Bros. so Nintendo is introducing special editions of the DSi and DSi XL to celebrate. Sadly these consoles are for Japan only. The big N will also be launching a Super Mario Collection Special Pack alongside.

The pack includes a version of Super Mario All-Stars for the Wii, a soundtrack CD, and a “Super Mario History, 1985 to 2010″ booklet with some extra materials like initial development planning sheets handwritten by Shigeru Miyamoto. Also for Japan only.

Nintendo is cutting the price of the DSi to $149.99 and the DSi XL to $169.99 (down $20 each) on September 12 in North America. They already dropped prices in the UK and Japan in June.

We still have no word what the 3DS will cost when it arrives, but we should get an announcement at the end of this month. In the meantime the big N will be selling tons of these models.

Looks like that extra-large DSi LL, unveiled in Japan this morning will be coming to North America and Europe in the first quarter of 2010. It will be known as the Nintendo DSi XL in North America and Europe, which is fitting given all of the XL sized Americans who will be buying it.

This new DSi offers a screen 93% larger than the current Nintendo DS Lite with a better view angle, a longer touch screen stylus, and preinstalled Nintendo DSiWare™ software. The new version will arrive in North America and Europe in the first quarter of 2010.
