Nintendo will no longer produce DS Lites
An internal GameStop memo is purporting that the DS Lite is no longer in production and will no longer be available when current stocks run out. Stores have also been instructed to remove any promotional materials for the product. Sad news if your looking for a region free Nintendo handheld.
Never fear for the DSi and DSi XL are still around and are obviously better than the DS Lite. As for the region free DS gaming, the 3DS's backwards compatibility can cover that.
