Nintendo has released a new short trailer showcasing the newly-announced, New 3DS and New 3DS XL.
The trailer is below, and it's very short indeed. It mainly focuses on the improved 3D, the screen, and the NFC capability. This iteration also boosts improved CPU and a better camera.
Nintendo announced the new iterations last month. They're both expected in Japan this October, with no date for the west as of yet.
Note that 3DS LL is how the XL is referred to in Japan.
