It wasn't the most hyped launch ever, but Nintendo's DSi had itself a fine little opening weekend, with 300,000 units moving in the US and Europe each. Not bad at all, considering that the first DS only sold 500,000 units in its first entire week in the US -- we're guessing the DSi will manage to meet that mark when the final numbers all come in. So, anyone out there pick one up?Filed under: Gaming
