Nintendo will bolster the 3DS' capabilities in November by adding 3D video recording.
Currently the system can only take static pictures in 3D.
The feature will be added in a forthcoming firmware upgrade which will also include refinements to the Mii Plaza and eShop.
Nintendo boss Satoru Iwata announced the update at the company's pre-TGS gathering last night.
Iwata hinted that Plaza upgrades would include new SpotPass activities for those who'd already completed the existing Puzzle Swap and StreetPass Quest minigames.
