Nintendo Announces The 2DS
The system is compatible with all 3DS and DS games. Its two screens are the same size as those of the original 3DS, smaller than those on the Nintendo 3DS XL. The 2DS’ upper screen will not render graphics in 3D, though the system’s two outward-facing cameras will still take photos and video in 3D, saving those files on a memory card so that they can be transferred to hardware that does display stereoscopic 3D imagery.
Only Nintendo would put a 3D camera on a device that doesn’t have a 3D screen.
