With the continued delays in the release of Sony's PlayStation 3 and the Nintendo Wii, it seems that many current-gen console gamers aren't seeing anything worth buying. Game sales in the U.S. have taken a fairly large dip, falling by 10% over the last month. That number applies only to console games, and likely the bigger focus on school years ending and college students taking finals has had an impact on this. Sales tend to rely on things people see as new and worth trying, and nothing particularly interesting, sans the DS Lite, has been released lately. The DS Lite has been faring well, on track with the sales of the original DS, and may help pick those sales numbers up as Summer arrives.
