Siliconera reports that Nintendo has filed for a new trademark in Japan on something called the "DS Houi Sensor Card." As the site points out, the full English translation is "DS Direction Sensor Card," leading to (inevitable) speculation that Nintendo is planning DS games with built-in direction / motion tracking.
Current games, such as Tony Hawk's Motion, utilize custom cartridges -- inserted into the DS' GBA slot -- for added functionality. But with the DSi ditching GBA cart compatibility, Nintendo had to do something; this may be a sign of more nifty gimmicks to come on the handheld, which is (possibly) soon-to-be-released in North America.
