The Nintendo DSi was released in Japan on Saturday, and the initial production run of 200,000 units has already sold out. 1Up has done some comparisons to the DS, and they have a video feature tour of the new hardware (which, predictably, has already been hacked). The image editing software is reported to be rather bare-bones, and the browsing is slow, but both features could likely be used with games in interesting ways. Nintendo will be launching a series of WarioWare games to demonstrate the DSi's capabilities. The DSi will likely reach North America next summer.
