Earlier today, Nintendo announced a new portable system, the Nintendo 3DS. This system will offer 3D graphics without the need for special 3D glasses. This system will likely be released during Nintendo’s next fiscal year, meaning sometime between April 2010 and March 2011.
Further speculation leads to other conclusions, primarily that this is the start of a new hardware line for Nintendo, rather than just a continuation of the DS line.
The 3DS will be backwards compatible with the entire library of DS/DSi titles (which implies that the 3DS will, by necessity, have the same two cameras that the DSi has).
Expect a full reveal of the 3DS at this year’s Electronic Entertainment Expo (E3), which takes place mid-June.
