When it was first announced last year at the Electronic Entertainment Expo, Nintendo heralded its 3DS gaming system as the next big thing in handheld gaming. Many users were excited, with images of Mario dancing around in 3D and games such as Mario Kart and others getting new life breathed into them. The system's launch in March, however, told a different story. The launch turned out to be one of the most lackluster for a system in recent memory (perhaps outdone by the Sega Saturn's rush to stores years before) and, months later, it still feels like it's running behind. But some new warning signs indicate that the once-promising handheld is in all kinds of trouble.
